ARM: introduce sync_caches_for_execution
We have several places in the code which which prepares just modified code
for execution. This is done differently in all the places, so add a common
function to be used by all.
Most places called arm_early_mmu_cache_flush(). This function includes
invalidating the instruction cache, so doing it again is unnecessary.
Sometimes we had arm_early_mmu_cache_flush() inside #ifdef CONFIG_MMU.
The ifdef seems unnecessary since we do not have it consistently, so
remove the ifdef.
Some early i.MX xload code had icache_invalidate() but forgot to flush
the caches. Replace the instruction cache invalidation with
sync_caches_for_execution().
