> There are following PCDs in IntelFsp2WrapperPkg for microcode location:
> 
> * IntelFsp2WrapperPkg:
>   PcdCpuMicrocodePatchAddress
>   PcdCpuMicrocodePatchRegionSize
>   PcdFlashMicrocodeOffset
> 
> The change simplify the platform code to use following PCDs instead:
> * MinPlatformPkg
>   PcdFlashFvMicrocodeOffset
>   PcdFlashFvMicrocodeBase = $(BIOS_BASE) + PcdFlashFvMicrocodeOffset
>   PcdFlashFvMicrocodeSize
>   PcdMicrocodeOffsetInFv <NEW>
