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.
