Subject: [PATCH 3/3] ARM64: dts: stratix10: Add stmmac ptp_ref clock

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

Add the default stmmac ptp_ref clock for stratix10.  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
inappropriate for the stratix10.  The default ptp_ref clock is
STRATIX10_PERI_EMAC_PTP_CLK in the clock manager.
