[PATCH] arch: arm: socfpga: arria10: Add stmmac ptp_ref clock to socdk devicetree

[dwesterg]

From: Dalon Westergreen <dalon.westergreen@linux.intel.com>

Add the stmmac ptp_ref clock as it is configured in the arria10 socdk.
The stmmac driver defaults the ptp_ref clock to the main stmmac clock
if the ptp_ref clock is not set in the devicetree.  This is inapprotiate
for the arria10 socdk.

These should go into the base arria10 dtsi at socfpga_arria10.dtsi?
Should the other gmacs get the same updates?

Also the patch header should be "ARM: dts: arria10:"

Agreed, I will send a new patch set that addresses cv/av, a10, and s10.
