m68knommu: merge bit definitions for version 3 ColdFire cache controller
All version 3 based ColdFire CPU cores have a similar cache controller. Merge all the exitsing definitions into a single file, and make them similar in style and naming to the existing version 2 and version 4 cache controller definitions. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
