m68knommu: create common DMA table for ColdFire CPUs
Move the ColdFire DMA address table into its own file, and out of each of the different CPU config files. No need to have a copy of it in each of the config setup files. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
