parentm68knommu: fix multi-function pin setup for FEC module on ColdFire 523x (diff)

m68knommu: clean up Pin Assignment definitions for the 54xx ColdFire CPU
The Pin Assignment register definitions for the ColdFire 54xx CPU family are inconsistently named and defined compared to the other ColdFire part definitions. Rename them with the same prefix as used on other parts, MCFGPIO_PAR_, and make their definitions include the MCF_MBAR periphperal region offset. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
