Current implementation of SetStaticPageTable routine in PiSmmCpuDxeSmm
driver will check a global variable mPhysicalAddressBits, and eventually
cap any value larger than 39 at 39.
This global variable is used in ConvertMemoryPageAttributes, which backs
SmmSetMemoryAttributes and SmmClearMemoryAttributes. Thus for a processor
that supports more than 39 bits width, trying to mark page table regions
higher than 39-bit will always return EFI_UNSUPPROTED.
This change updated the interface of SetStaticPageTable function to take
PhysicalAddressBits as an input parameter, in order to avoid changing/
accessing the global variable.
