Subject: [PATCH 1/2] arm64: dts: rockchip: rk3399-orangepi: Add ethernet phy.

Enables INTB.
The wiring is the same as the nanopi4, so this is heavily based on:
- [1a4e6203f0c] arm64: dts: rockchip: Add nanopi4 ethernet phy
- [bc43cee88aa] arm64: dts: rockchip: Update nanopi4 phy reset properties
by Robin Murphy.
