Idtr might be changed inside of FSP. 32bit FSP only knows the <4G address.
If IDTR.Base is >4G, FSP can not handle. So we need save/restore IDTR here.
Interrupt is already disabled here, so it is safety to update IDTR.

because most platforms use such logic.
PcdDataBaseHobGuid GuidHob is excluded because PCD database in FSP is different with the one in PEI.

The FSP API is always 32bit, but FspNotifyDxe might load to >4G memory. In order to make thunk work, we need reload FspNotifyDxe to <4G memory.

IntelFspWrapperPkg, In the file FspInitPeiV1.c and FspInitPeiV2.c, there are function calling:
GetStackInfo (BootMode, FALSE, &StackBase, &StackSize);
But the function GetStackInfo() defined as EFI_STATUS EFIAPI GetStackInfo (
IN UINT32 BootMode,
IN BOOLEAN FspInitDone,
OUT UINT64 *StackSize,
OUT EFI_PHYSICAL_ADDRESS *StackBase
)
It should be GetStackInfo (BootMode, FALSE, &StackSize, &StackBase);

There are two FSP images at different locations in a flash (one factory version is read only and other in updatable version)
TempRamInit, FspMemoryInit and TempRamExit are executed from factory version and FspSiliconInit/NotifyPhase will be executed from updatable version.
