Cortex-M processors don't have an MMU, but can still have caches that need software management, so on those platforms we don't want to include the MMU related functions. While here, remove an outdated section of a comment referring to deprecated cache maintenance functions which no longer exist. Change-Id: I6f0fe694560bdee25ed7c69a846bf46e3e544cb1
