UefiCpuPkg:Limit PhysicalAddressBits in special case
When creating smm page table, limit maximum
supported physical addresses bits returned by
CalculateMaximumSupportAddress() to 47 if
5-Level Paging is disabled.
This commit is to avoid issue that more than
47-bit physical addresses are requested in smm
page table when 5-level paging is disabled.
4-level paging supports translating 48-bit
linear addresses to 52-bit physical addresses.
Since linear addresses are sign-extended,
linear-address space of 4-level paging is:
[0, 2^47-1] and
[0xffff8000_00000000, 0xffffffff_ffffffff].
So only [0, 2^47-1] linear-address range maps
to the identical physical-address range when
5-Level paging is disabled.
