Configure flash timings dynamically to match the system clock.  Reconfigure
timings after flash writes.

Changes are:
- ports/rp2/main.c: Set default flash timings.
- ports/rp2/modmachine.c: Configure optimal flash timings on freq change.
- ports/rp2/rp2_flash.c: Reconfigure flash when leaving critical section.

89eea0f5e8 rp2/rp2_flash: Support flash writes from PSRAM.
Add a 256 byte (FLASH_PAGE_SIZE) SRAM copy buffer to allow copies from
PSRAM to flash.  This would otherwise hardfault since PSRAM is disabled
when doing a write to flash.

Changes are:
- ports/rp2/rp2_flash.c: Add 256 byte (flash page size) SRAM copy buffer
                         for PSRAM to flash copies.
- ports/rp2/rp2_flash.c: Invalidate the XIP cache to purge any PSRAM
                         data before critical flash operations.

b7d5caf2a3 rp2/mpconfigport: Configure heap for PSRAM.
PSRAM will be used exclusively if MICROPY_GC_SPLIT_HEAP == 0, it will be
added to RAM if MICROPY_GC_SPLIT_HEAP == 1, and the system will fall back
to RAM only if it's not detected.

Due to the size of PSRAM, GC stack was overflowing and causing the GC to
scan through the entire memory pool.  This caused noticable slowdowns
during GC.  Increase the stack from 256 to 4096 bytes to avoid overflow and
increase the stack entry type size to accomodate 8MB+ PSRAM.

Changes are:
- ports/rp2/mpconfigport.h: Make split-heap optional and enable by default.
- ports/rp2/mpconfigport.h: Increase GC stack entry type to uint32_t.
- ports/rp2/mpconfigport.h: Raise GC stack size.

11f057dd9a rp2: Add support for PSRAM with auto-detection.
Performs a best-effort attempt to detect attached PSRAM, configure it and
*add* it to the MicroPython heap.  If PSRAM is not present, should fall
back to use internal RAM.

Introduce two new port/board defines:
- MICROPY_HW_ENABLE_PSRAM to enable PSRAM.
- MICROPY_HW_PSRAM_CS_PIN to define the chip-select pin (required).

Changes are:
- ports/rp2/rp2_psram.[ch]: Add new PSRAM module.
- ports/rp2/main.c: Add optional PSRAM support.
- ports/rp2/CMakeLists.txt: Include rp2_psram.c.
- ports/rp2/mpconfigport.h: Add MICROPY_HW_ENABLE_PSRAM.
- ports/rp2/modmachine.c: Reconfigure PSRAM on freq change.

f96417dbf2 rp2/cyw43_configport: Fix cyw43 mDNS by properly starting mDNS on netif.
The rp2 port has an incomplete mDNS implementation.  The code in `main.c`
calls `mdns_resp_init()` which opens the UDP socket for mDNS.  However, no
code in the cyw43 driver makes the proper calls to `mdns_resp_add_netif()`
and `mdns_resp_remove_netif()` to send the announce packets.  The wiznet5k
driver does make these calls and was used as a model for these changes.

This commit attempts to address this by very small changes to the
`ports/rp2/cyw43_configport.h` file.  The change uses new cyw43 driver
hooks to map the driver macros `CYW43_CB_TCPIP_INIT_EXTRA` and
`CYW43_CB_TCPIP_DEINIT_EXTRA` to the appropriate lwIP mDNS calls.

Fixes issue #15297.

cccac2cc01 rp2,esp32,extmod: Implement UPDATE_SUBMODULES in CMake.
Rather than having Make calling CMake to generate a list of submodules and
then run a Make target (which is complex and prone to masking other
errors), implement the submodule update logic in CMake itself.

Internal CMake-side changes are that GIT_SUBMODULES is now a CMake list,
and the trigger variable name is changed from ECHO_SUBMODULES to
UPDATE_SUBMODULES.

The run is otherwise 100% a normal CMake run now, so most of the other
special casing can be removed.

2b2a431878 rp2/machine_uart: Fix unintended UART buffer allocation on init().
The buffer was be reset on every call to uart.init().  If no sizes were
given, the buffer was set to the default size 256.  That made problems e.g.
with PPP.

This commit fixes it, keeping the buffer size if not deliberately changed
and allocating new buffers only if the size was changed.

23fb171b80 rp2/mpnetworkport: Refactor out cyw43_has_pending global variable.
A better indication of whether a cyw43 event is pending is the actual flag
in the PendSV handler table. (If this fails, could also use the GPIO
interrupt enabled register bit).

This commit was needed of a previous version of the fix in the parent
commit, but it turned out not strictly necessary for the current version.
However, it's still a good clean up.

6fa498cba1 rp2/mpnetworkport: Fix lost CYW43 WiFi events when using both cores.
There's a very odd but predictable sequence of events that breaks Wi-Fi
when using both cores:

1) CPU1 calls pendsv_suspend() - for example sleep() causes
   a softtimer node to be inserted, which calls pendsv_suspend().
2) CYW43 sends wakeup IRQ. CPU0 GPIO IRQ handler schedules PendSV
   and disables the GPIO IRQ on CPU0, to re-enable after
   cyw43_poll() runs and completes.
3) CPU0 PendSV_Handler runs, sees pendsv is suspended, exits.
4) CPU1 calls pendsv_resume() and pendsv_resume() sees PendSV
   is pending and triggers it on CPU1.
5) CPU1 runs PendSV_Handler, runs cyw43_poll(), and at the end
   it re-enables the IRQ *but now on CPU1*.

However CPU1 has GPIO IRQs disabled, so the CYW43 interrupt never runs
again...

The fix in this commit is to always enable/disable the interrupt on CPU0.
This isn't supported by the pico-sdk, but it is supported by the hardware.

Fixes issue #16779.

It's common with write-only SPI displays for MISO to be repurposed as a
register select or data/command pin.

While that was possible by setting up the pin after a call to
`machine.SPI()` this change makes `machine.SPI(miso=None)` explicit.

Not enabled by default on any board.  A board can enable a ROMFS partition
by defining `MICROPY_HW_ROMFS_BYTES` in its `mpconfigboard.h` file.  For
example:

    #define MICROPY_HW_ROMFS_BYTES (128 * 1024)

The ROMFS partition is placed at the end of the flash allocated for the
firmware, giving less space for the firmware.  It then lives between the
firmware and the read/write filesystem.

bb4ec886f8 rp2/machine_i2c: Make I2C bus ID arg optional with default.
This commit gives the option to not pass an I2C Bus ID when creating a
machine I2C object.  If the ID is not provided, the default bus ID (which
is `PICO_DEFAULT_I2C`) is used.

This allows users to simply declare an I2C object with `machine.I2C()`
without passing any arguments, thus creating an object with the default I2C
ID, SCL, and SDA.

71df9d0636 rp2: Fix build failure if threads are disabled.
Regression in 3af006ef meant that pendsv.c no longer compiled if threads
were disabled in the build config. Add an implementation based on the
earlier one (simple counter) for the non-threads case.

It seems like with the current usage patterns there's no need for the
counter to be incremented/decremented atomically on a single core config.

b11ba39c57 rp2/modules: Fix memory leak and logic bug in handling of _pio_funcs.
The `rp2` package use a global dict `_pio_funcs` to populate a namespace
for `@asm_pio` functions to be executed in.  That dict is not cleaned up
after use, keeping references to bound methods of a `PIOASMEmit`.  By not
setting/clearing all the functions, `asm_pio_encode` unintentionally allows
the use of the old directives (harmless) as well as `jmp` (in general,
produces the wrong output).

Fix that by making sure `_pio_funcs` is returned to its original state
after using it:

- For `@asm_pio` update the target dict from `_pio_funcs` and then set
  additional functions as needed, leaving `_pio_funcs` unchanged.

- For `asm_pio_encode`, borrow `_pio_funcs` to use as globals (avoiding a
  bunch of memory alloc/free) but delete the instruction entries after use.

calling `machine.lightsleep()` overwrites RP2xxx registers `SLEEP_EN0` and
`SLEEP_EN1` with their power on default values.

Prior to that commit the register values were saved on entry to lightsleep
and restored before returning.

This lwIP configuration file has options that are common to all ports, and
the ports are updated to use this file.  This change is a no-op, the lwIP
configuration remains the same for the four ports using this common file.

This reduces code duplication, keeps the ports in sync, and makes it easier

4a6c246008 rp2/mphalport: Add mp_hal_is_pin_reserved() function.
As cyw43 pins might be dynamic, add a function that returns if a pin is
reserved.  This is used by `MICROPY_HW_PIN_RESERVED` to prevent the pin IRQ
from being reset across a soft-reset.

30163e0ae4 rp2/cyw43_configport: Define cyw43 pins.
The cyw43 pins used to be hardcoded and `CYW43_PIN_WL_HOST_WAKE` and
`CYW43_PIN_WL_REG_ON` were in the `pico_w.h` board header.

This has been changed so the board header just defines the "default
version of the pins, e.g. `CYW43_DEFAULT_PIN_WL_HOST_WAKE`,
`CYW43_DEFAULT_PIN_WL_REG_ON` etc.

Set the pin values in `cyw43_configport.`h so `cyw43-driver` sees them and
allow them to be changed at runtime (dynamic) if required.
