MX6 and mx28 support enhanced DMA descriptor buff to support 1588
ptp. But MX25, MX3x, MX5x can't support enhanced DMA descriptor buff.
Check fec type and choose correct DMA descriptor buff type.
Remove static config CONFIG_FEC_PTP.
ptp function will be auto detected.

This patch adds a driver for the FEC(MX6) that offers time
stamping and a PTP haderware clock. Because FEC\ENET(MX6)
hardware frequency adjustment is complex, we have implemented
this in software by changing the multiplication factor of the
timecounter.

when the link is 10 Mbps and the mode is RMII, it's necessary
to set FRCONT to 1 in MIIGSK_CFGR to divide the RMII source
clock by 10 in order to support 10 Mbps operations.

Move the Freescale drivers into drivers/net/ethernet/freescale/ and
make the necessary Kconfig and Makefile changes.
