ARMV7: add a function to disable MMU entries
It is useful to be able to lock out certain address ranges,
NULL being the most important example.
void mmu_disable_range(unsigned long start_mb, unsigned long size_mb)
will allow us to lock out selected virtual addresses on MiB boundaries.
As in other ARM mmu functions, the addresses and quantities are in units
of MiB.
