REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3893 1.Added EFIAPI to FspNotifyPhasePeimEntryPoint, SwapStack and PEI_CORE_ENTRY. 2.Treat both MAX_ADDRESS and MAX_UINT32 as invalid address for FSP global data in FspApiCallingCheck(). 3.Changed AsmReadEsp to AsmReadStackPointer. 4.Changed the type of the return value of AsmReadStackPointer from UINT32 to UINTN. 5.Changed the type of TemporaryMemoryBase, PermenentMemoryBase and BootLoaderStack from UINT32 to UINTN. 6.Some type casting to pointers are UINT32. Changed them to UINTN to accommodate both IA32 and X64. 7.Corrected some typos.
