MdeModulePkg/PiSmmCore: remove NX attr for SMM RAM
If PcdDxeNxMemoryProtectionPolicy is set to enable protection for memory
of EfiReservedMemoryType, the BIOS will hang at a page fault exception
during starting SMM driver.
The root cause is that SMM RAM is type of EfiReservedMemoryType and
marked as non-executable. The fix is simply removing NX attribute for
those memory.
