York Sun 7f9b9f318f armv8: mmu: Add a function to change mapping attributes
Function mmu_change_region_attr() is added to change existing mapping
with updated PXN, UXN and memory type. This is a break-before-make
process during which the mapping becomes fault (invalid) before final
attributres are set.
