This short series implements support for the laptop keyboards on the
Apple Silicon Mac laptops.  These keyboards are connected to an SPI
bus, so this adds a driver for the SPI controller integrated on the
SoC, as well as the driver for the keyboard itself.  This makes it
possible to interact with U-Boot and EFI applications without the
need for an external USB keyboard.
