[PATCH] arm64: dts: rockchip: Add compatible for Ethernet PHY

[Adrian Kossmann]

Without the compatible string the Ethernet PHY is not bound to the
correct driver. This causes link instability under load, with throughput
eventually dropping to zero.
Add the explicit PHY ID compatible to ensure the proper driver is selected.
