drivers/intel/fsp2_0: Fill EFI_CPU_PHYSICAL_LOCATION structure information
Latest EDK2 code inside
"UefiCpuPkg\Library\RegisterCpuFeaturesLib\CpuFeaturesInitialize.c"
is now looking for EFI_CPU_PHYSICAL_LOCATION structure variables hence
coreboot need to fill required information (package, core and thread

TEST=Able to see package, core and thread information as part of FSP
debug log.
