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.
