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.
