504adc689b stm32/boards/NUCLEO_G474RE: Restore disabled modules on g474re.
Among other things, the framebuf module is missing on NUCEO_G474RE. This
board seems to disable a lot of modules, while other *E boards with the
same flash configuration (eg NUCLEO_F411RE) don't seem to disable any
modules in this way.

So, remove all of the lines disabling modules to make it consistent with
other boards.

9c2b0cd2e3 stm32/usbd_conf: Fix build for boards with USB disabled.
Some boards (eg NUCLEO_G0B1RE and NUCLEO_G474RE) have USB disabled but
still configure MICROPY_HW_USB_FS/HS for the cases where USB does get
enabled.  Such a configuration should not build any of the code in
`usbd_conf.c`, nor the USB interrupt handlers.

63c94fe73e stm32: Fix init sequence of USB hardware and TinyUSB stack.
This commit fixes the initialization sequence for TinyUSB when enabled on
the stm32 port:

- Following other ports, `mp_usbd_init()` should be called just after
  running `boot.py`, to give the user a chance to configure USB.

- Hardware initialization (via `pyb_usbd_init()`) should only occur once,
  the first time TinyUSB is started up.  This is achieved by adding a hook
  to the shared TinyUSB bindings to call `pyb_usbd_init()`, and only do the
  hardware init if TinyUSB was not already initialized.

Also, `pyb_usbd_init()` is renamed `mp_usbd_ll_init()` to make it match
with the rest of the stared TinyUSB binding code.

9f87b79142 stm32/eth: Implement zero-copy of lwIP pbufs for TX path.
This option (currently only enabled for N6) allows the TX path to hold on
to a pbuf reference while the DMA accesses the pbuf's memory directly,
instead of copying the entire pbuf data into the internal buffers.

This is necessary to achieve gigabit speeds on the N6, although actually
achieving that speed requires higher up parts of the stack to be efficient
as well.

ba5711a011 stm32/eth: Move DMA TX/RX index variables to normal RAM.
RAM shared with DMA needs caching disabled, which is slower for the MCU to

TinyUSB's `dwc2_phy_init()` only sets the PWRDWN bit in the GCCFG register
but doesn't configure VBUS sensing, which is required for the DWC2 USB
controller to detect host connection on STM32F4 and STM32F7 series.

Without VBUS sensing configured, USB devices fail to enumerate on these
platforms when using the TinyUSB stack, while the legacy STM32 USB stack
works because it includes this configuration.

This commit adds VBUS sensing configuration in `pyb_usbd_init()` for
TinyUSB mode on STM32F4/F7:
- When VBUS detect pin is configured (typically PA9): Enable "B device"
  VBUS sensing (USB_OTG_GCCFG_VBUSBSEN)
- When no VBUS pin: Force VBUS valid (USB_OTG_GCCFG_NOVBUSSENS)

Tested on:
- NUCLEO-F429ZI: USB now enumerates successfully (CDC + MSC)
- NUCLEO-H563ZI: No regression (STM32H5 uses different register layout)

9bb266e311 stm32/usb: Add support for using TinyUSB stack.
This commit adapts the stm32 port to allow switching from STM USB stack to
TinyUSB stack.

Using TinyUSB improves consistancy with other MicroPython ports and brings
in the ability to use the runtime USB definition support recently added to
other TinyUSB based ports.

By default the existing STM USB stack is used.  TinyUSB can be enabled in a
board configuration with:

    #define MICROPY_HW_TINYUSB_STACK (1)

Or, it can be enabled from the command line with:

    make -C ports/stm32 CFLAGS_EXTRA='-DMICROPY_HW_TINYUSB_STACK=1'

Implemented the keyword-only parameter `invert` for the `UART.init` method
in accordance with the docs:
- added constants `UART.INV_TX` and `UART.INV_RX`
- added the new `invert` keyword parameter to the `uart_init` function
- adapted the `uart_init` call
- added invert setting to `uart_print` output

The feature applies only to STM32H7.

For STM32H7, the following macro's value are different by ADC's version:
* ADC_CAL_ADDRESS
* ADC_CAL1
* TEMPSENSOR_CAL2_ADDR

Using macros defined by HAL become less dependent on ADC's version.

007f127a61 all: Simplify mp_int_t/mp_uint_t definition.
Assuming proper C99 language support, we can select "the int type as big as
a pointer" (most of the time) or "the 64-bit int type" (nanboxing with
REPR_D), and then define everything else automatically.

This simplifies port configuration files.  And the types can still be
overridden if needed.

49f2a1f0ed stm32/timer: Support soft IRQ timer callbacks.
machine.Timer() has inconsistent behaviour between ports: some run

As on the rp2 port, add support to the stm32 port for a hard= argument
to explicitly choose between these, setting the default to True to match
the existing behaviour.
