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

[dwesterg]

From: Dalon Westergreen <dalon.westergreen@xxxxxxxxxxxxxxx>

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.
