ArmPlatformPkg: PL031RealTimeClockLib: Set MMIO Memory XP
PL031RealTimeClockLib will clear EFI_MEMORY_XP if a platform
has set it for MMIO memory when it does not include that bit
in its SetMemoryAttributes call. This region is not intended
to be executed from and as such the lib should explicitly set
EFI_MEMORY_XP to this region.
