m68knommu: fix cache flushing for the 527x ColdFire processors
Fix cache flushing for the 527x ColdFire processors Its CACR register format is slightly different. Along with this add support for flushing the 523x cache, which uses the same format as the 527x ColdFire's, and was missing flush support. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
