drivers/intel/fsp2_0: Add FSP 2.2 specific support
• Based on FSP EAS v2.1 – Backward compatibility is retained.
• Add multi-phase silicon initialization to increase the modularity of the
FspSiliconInit() API.
• Add FspMultiPhaseSiInit() API
• FSP_INFO_HEADER changes
o Added FspMultiPhaseSiInitEntryOffset
• Add FSPS_ARCH_UPD
o Added EnableMultiPhaseSiliconInit, bootloaders designed for
FSP 2.0/2.1 can disable the FspMultiPhaseSiInit() API and
continue to use FspSiliconInit() without change.
FSP 2.2 Specification:
