arm64/mm: Add PROT_DEVICE_nGnRnE and PROT_NORMAL_WT
UEFI spec 2.5 section 2.3.6.1 defines that
EFI_MEMORY_[UC|WC|WT|WB] are possible EFI memory types for
AArch64.
Each of those EFI memory types is mapped to a corresponding
AArch64 memory type. So we need to define PROT_DEVICE_nGnRnE
and PROT_NORMWL_WT additionaly.
MT_NORMAL_WT is defined, and its encoding is added to MAIR_EL1
when initializing the CPU.
