arm64: dts: allwinner: orangepi-zero-plus: fix PHY mode

Browse Source 
[ Upstream commit 08d2061ff9 ]

Orange Pi Zero Plus uses a Realtek RTL8211E RGMII Gigabit PHY, but its
currently set to plain RGMII mode meaning that it doesn't introduce
delays.

With this setup, TX packets are completely lost and changing the mode to
RGMII-ID so the PHY will add delays internally fixes the issue.
