mtd: Disable slram and phram when locked down

The slram and phram drivers both allow mapping regions of physical
address space such that they can then be read and written by userland
through the MTD interface.  This is probably usable to manipulate
hardware into overwriting kernel code on many systems.  Prevent that
if locked down.
