bsps/zynqmp: Fix and update device trees

Add ref-clock-num identifiers to the device tree to ensure that
interfaces use the correct clocks even when some are not used due to
unconnected MII busses. This also adjusts the default ZynqMP PHY
attachment to RGMII-ID which was the default before device trees were
introduced.
