m68knommu: Fixed GPIO pin initialization for CONFIG_M5271 FEC.
This processor only have one FEC and its MDIO pins are located at a different offset than the code used for the current CONFIG_M527x. Tesed on M5271EVB eval platform. Without this patch the FEC driver will report no PHY attached if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.
