[PATCH] arm64: zynqmp: add ref_clk property for REFCLKPER calculation

[Michal Simek]

From: Piyush Mehta <piyush.mehta at amd.com>

Added ref_clk 'ref' property for GUCTL_REFCLKPER and GFLADJ_REFCLK_FLADJ
calculation. This property configure correct value for SOF/ITP counter
and period of ref_clk.
This patch adds 'ref' property for both dwc3_0 and dwc3_1 cores.
