drivers/intel/fsp2_0: Add new config option to support FSP CAR 

CPU_MICROCODE_CBFS_LEN and CPU_MICROCODE_CBFS_LOC configs pass the CPU
microcode length and base address in CBFS to FSPT binary as init parameters.

Add new config FSP_T_XIP in Kconfig, which is selected by platform config.
If FSP_T_XIP is selected, then relocate FSPT binary while adding it in CBFS
so that it can be executed in place.

BUG= None
TEST= Build for both CFL RVP11 & RVP8 and verified for successfull CAR setup.
