The LPRTC peripheral is a 32-bit counter with a 16-bit prescaler. It's
configured here to count at 1Hz (to get maximum date range) and then the
prescaler value is used to get 30 microsecond resolution. That's
essentially a 32+15=47-bit counter.

Now raises an exception if the pin doesn't support the alternate function
unit number and line type, eg UART0_TX (previously it only checked the
peripheral).

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.
