Rename cache coherency functions.

Browse source 
The old cache coherency function names where wrong and misleading.
The new names are (purposely different from vendor manuals)
*  commit_* (write-back only)
*  discard_* (removing lines from cache only)
*  commit_discard_* (write-back and removing lines from cache)

It's suspected the old names have led to wrong uses. The old names still exist
(as aliases) so every call via the old names need to be double checked and changed
to the new name.
