[PATCH] sunxi: enable MMU_PGPROT proper page table protection

[Andre Przywara]

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.
Please report on the list or on IRC if bisecting ends at this patch.

Hi,

I am planning on merging this ASAP, to get some exposure and use the time
until the release for wider testing. If worst comes to the worst, we can
revert it still before July.

Cheers,
Andre
