[PATCH 2/3] arm64: dts: rockchip: move reset to dedicated eth-phy node on ringneck

[Quentin Schulz]

From: Heiko Stuebner <heiko.stuebner at cherry.de>

Using snps,reset-* properties to handle the ethernet-phy resets is
deprecated and instead a real phy node should be used.

Move the Ringneck phy-reset properties to such a node
