Merge branch 'fec-next'

Fugang Duan says:

====================
net: fec: add Wake-on-LAN support

The patch series enable FEC Wake-on-LAN feature for i.MX6q/dl and i.MX6SX SOCs.
FEC HW support sleep mode, when system in suspend status with FEC all clock gate
off, magic packet can wake up system. For different SOCs, there have special SOC
GPR register to let FEC enter sleep mode or exit sleep mode, add these to platform
callback for driver' call.

Patch#1: add WOL interface supports.
Patch#2: add SOC special sleep of/off operations for driver's sleep callback.
Patch#3: add magic pattern support for devicetree.
====================
