ARM: 9247/1: mm: set readonly for MT_MEMORY_RO with ARM_LPAE
MT_MEMORY_RO is introduced by commit 598f0a99fa8a ("ARM: 9210/1:
Mark the FDT_FIXED sections as shareable"), which is a readonly
memory type for FDT area, but there are some different between
ARM_LPAE and non-ARM_LPAE, we need to setup PMD_SECT_AP2 and
L_PMD_SECT_RDONLY for MT_MEMORY_RO when ARM_LAPE enabled.
non-ARM_LPAE 0xff800000-0xffa00000 2M PGD KERNEL ro NX SHD
ARM_LPAE 0xff800000-0xffc00000 4M PMD RW NX SHD
ARM_LPAE+fix 0xff800000-0xffc00000 4M PMD ro NX SHD
