This will involve:

  • Proper pin in-use checking.
  • Pin mux info in the pin objects.
  • Support for the ARM PL011 UART.
  • Support for the mini-SPI and regular ones.
  • Updating I2C for the full muxing.

Add full pin mux info and use it for I2C
2433c95 
All I2C peripherals should be usable now. This also adds pin
in-use tracking and resetting.

Full UART support for RPI
92a4261 
This adds PL011 UART support which is more plentiful.

It also:
* Fixes PI4 build by including .dtb files on the SD card.
* Enables the activity LED as the status LED on PI4 and CM4 I/O.
* Adds that LED as board.LED.

Fixes #5650 and progress on #5629
