Table 8 of UEFI 2.5 section 2.3.6.1 defines mappings from EFI
memory types to MAIR attribute encodings for arm64.
If the physical address has memory attributes defined by EFI
memmap as EFI_MEMORY_[UC|WC|WT], return approprate page protection
type according to the UEFI spec. Otherwise, return PAGE_KERNEL.

V2: Changed arm64's implementation of arch_apei_get_mem_attributes()
from inline function to out of line function, based on Ingo's
feedback.

Looks fine to me, though it appears to be missing Ard's Reviewed-by
tag (the only change from the previous version is that it's no longer
inline).

Ingo, are you going to pick up this patch series and apply it directly
to tip if you're OK with this version?
