sunxi: enable MMU_PGPROT proper page table protection
Select the new MMU_PGPROT Kconfig symbol for all Allwinner board builds,
to use a write-protected .rodata, non-executable .data and .rodata
sections, and non-writable .text sections.
This might trigger runtime exceptions in misbehaving drivers, which
should then be fixed.
