Add functions to disable the MMU at current exception level.
This patch adds capability to disable the MMU at current exception
level (NS-EL1 or EL2). It is implemented in assembler to ensure that
the data cache is cleaned and invalidated after the MMU is disabled
without any intervening cacheable data accesses.
