intel/fsp_rangeley: Load BSP microcode in bootblock
Load microcode to BSP in bootblock so later on the FSP TempRamInit call
will return with success. The updated fsp1_0 driver calls TempRamInit
API with dummy microcode, so FSP will not handle the microcode load. If
BSP is not loaded with microcode before calling TempRamInit API, the
call will fail with error No Valid Microcode Was Found.
