drivers/intel/fsp2_0: Implement EFI_MP_SERVICES_PPI structure APIs
This patch ensures to have below listed features:
1. All required APIs to create MP service structure.
2. Function to get MP service PPI status
MP specification here:
http://github.com/tianocore/edk2/blob/master/MdePkg/Include/Ppi/MpServices.h
coreboot design document here:
../Documentation/soc/intel/icelake/MultiProcessorInit.md
Supported platform will call fill mp_services structure so that FSP can
install the required PPI based on coreboot published structure.
BRANCH=none
BUG=b:74436746
TEST=Able to publish MP service PPI in coreboot.
