The EDIMM STARTER KIT i.Core 1.5 MIPI Evaluation is based on
the 1.5 version of the i.Core MX6 cpu module. The 1.5 version
differs from the original one for a few details, including the
ethernet PHY interface clock provider.

With this commit, the ethernet interface works properly:
SMSC LAN8710/LAN8720 2188000.ethernet-1:00: attached PHY driver

While before using the 1.5 version, ethernet failed to startup
do to un-clocked PHY interface:
fec 2188000.ethernet eth0: could not attach to PHY

Similar fix has merged for i.Core MX6Q but missed to update for DL.
