Add FEC support for Engicam i.CoreM6 dql modules.
Observed similar 'eth0: link is not ready' issue which was
discussed in [1] due rmii mode with external ref_clk, so added
clock node along with the properties mentioned by Shawn in [2]
FEC link log:
------------
$ ifconfig eth0 up
[ 27.905187] SMSC LAN8710/LAN8720 2188000.ethernet:00: attached PHY driver
[SMSC LAN8710/LAN8720] (mii_bus:phy_addr=2188000.ethernet:00, irq=-1)
[ 27.918982] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
