Brit Chesley efc7ccf906 MdeModulePkg/Bus/Spi/SpiBus: Adding SpiBus Drivers 
Added SpiBus DXE and SMM drivers. This code translates SPI requests from
the application layer into SPI Bus transactions on the SPI host
controller. The code is responsible for checking if the transaction is
valid, then setting up the SPI clock and chip select properly before
passing the bus transaction to the host controller.
