net: fec: Fix build for MCF5272
Commits 4c09eed9 (net: fec: Enable imx6 enet checksum acceleration) and baa70a5c (net: fec: enable pause frame to improve rx prefomance for 1G network) introduced functionality into the FEC driver which is not supported on MCF5272. The registers used to implement this functionality do not exist on MCF5272. Since register defines for MCF5272 are separate from register defines for other chips, building images for MCF5272 fails as follows. fec_main.c: In function 'fec_restart': fec_main.c:520:8: error: 'FEC_RACC' undeclared (first use in this function) fec_main.c:585:3: error: 'FEC_R_FIFO_RSEM' undeclared (first use in this function) fec_main.c:586:3: error: 'FEC_R_FIFO_RSFL' undeclared (first use in this function) fec_main.c:587:3: error: 'FEC_R_FIFO_RAEM' undeclared (first use in this function) fec_main.c:588:3: error: 'FEC_R_FIFO_RAFL' undeclared (first use in this function) fec_main.c:591:3: error: 'FEC_OPD' undeclared (first use in this function) Adding the missing register defines is not an option, since the registers do not exist on MCF5272. Disable the added functionality for MCF5272 builds.
