[PATCH 1/1 v2 net-next] net: fec: fix the build as module

[Frank Li]

Since commit ff43da86c69 (NET: FEC: dynamtic check DMA desc buff type) the
following build error happens when CONFIG_FEC=m

ERROR: "fec_ptp_init" [drivers/net/ethernet/freescale/fec.ko] undefined!
ERROR: "fec_ptp_ioctl" [drivers/net/ethernet/freescale/fec.ko] undefined!
ERROR: "fec_ptp_start_cyclecounter" [drivers/net/ethernet/freescale/fec.ko] undefined!

rename fec.c to fec_main.c
Build fec.o and fec_ptp.o into one fec.ko
