[PATCH 07/30] asm-generic: move sync_caches_for_execution declaration to <asm/cache.h>

[Ahmad Fatoum]

We have three architectures defining sync_caches_for_execution(). Have
them all do so in a header of the same name to allow using it in common
code later on, like in an EFI image loading routine.
