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().
