ENGR00181337-4 i.mx6 : i.mx6sl: Fix FEC RX CRC Error
Since FEC_RX_ER is not connected with PHY(LAN8720A), we need
either configure FEC_RX_ER PAD to other mode than FEC_RX_ER,
or configure FEC_RX_ER PAD to FEC_RX_ER but need pull it down,
otherwise, FEC MAC will report CRC error always. We configure
FEC_RX_ER PAD to GPIO mode here and remove the SW hack which
ignore the CRC error in fec driver
