m68knommu: make Coldfire 548x support more generic
The ColdFire 547x family of processors is very similar to the ColdFire 548x series. Almost all of the support for them is the same. Make the code supporting the 548x more gneric, so it will be capable of supporting both families. For the most part this is a renaming excerise to make the support code more obviously apply to both families. Signed-off-by: Greg Ungerer <gerg@uclinux.org>wifi-calibration
