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. Signed-off-by: York Sun <york.sun@nxp.com>
