This allows `machine.deepsleep(N)` to wake the device after the timout N
seconds.
Could probably also do the same thing for lightsleep.
Note that this uses the LPTIMER0 resource, which would not work if
`MICROPY_HW_SYSTEM_TICK_USE_LPTIMER` was ever enabled (it's currently never
enabled, so OK for now).

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.

The same MicroPython firmware is built for the HE but with slightly
different options, for example no USB.

This commit adds the beginning of a new alif port with support for Alif
Ensemble MCUs. See https://alifsemi.com/
Supported features of this port added by this commit:
- UART REPL.
- TinyUSB support, for REPL and MSC.
- Octal SPI flash support, for filesystem.
- machine.Pin support.
General notes about the port:
- It uses make, similar to other bare-metal ports here.
- The toolchain is the standard arm-none-eabi- toolchain.
- Flashing a board can be done using either the built-in serial bootloader,
or JLink (both supported here).
- There are two required submodules (one for drivers/SDK, one for security
tools), both of which are open source and on GitHub.
- No special hardware or software is needed for development, just a board
connected over USB.
OpenMV have generously sponsored the development of this port.
