Add IntelFsp2Pkg and IntelFsp2WrapperPkg.
Add FSP2.0 support.
This series of patch is to support FSP2.0 specification at
https://firmware.intel.com/sites/default/files/FSP_EAS_v2.0_Draft%20External.pdf
Some major updates include:
1) One FSP binary is separated to multiple components:
FSP-T, FSP-M, FSP-S, and optional FSP-O.
Each component has its own configuration data region.
2) All FSP-APIs use same UPD format - FSP_UPD_HEADER.
3) Add EnumInitPhaseEndOfFirmware notifyphase.
4) FSP1.1/FSP1.0 compatibility is NOT maintained.
5) We also add rename Fsp* to FspWrapper* in IntelFsp2WrapperPkg,
to indicate that it is for FspWrapper only.
IntelFspPkg and IntelFspWrapperPkg will be deprecated.
The new Intel platform will follow FSP2.0 and use IntelFsp2Pkg
and IntelFsp2WrapperPkg.
The old platform can still use IntelFspPkg and IntelFspWrapperPkg
for compatibility consideration.
