Subject: [PATCH v2 1/1 net-next] NET: FEC: dynamtic check DMA desc buff type

MX6 and mx28 support enhanced DMA descript buff to support 1588
ptp. But MX25, MX3x, MX5x can't support enhanced DMA descript buff.
Check fec type and choose correct DAM descript buff type.

Remove static config CONFIG_FEC_PTP.
ptp function will be auto detected.

Signed-off-by: Frank Li <Frank.Li@...escale.com>
---
change from v1->v2:
 1. remove CONFIG_FEC_PTP
 2. fix code style issue. pass checkpatch
 3. fix issue "return bdp++", return value is not added
 4. remove unnecessary module parameter fec_ptp_enable
 5. change get_nextdesc to fec_enet_get_nextdesc
