ARM: sun8i: h3: Enable EMAC with external PHY on Orange Pi Plus 2E
The Orange Pi Plus 2E, unlike the Orange Pi PC and PC Plus which its schematics are based on, uses an external Realtek RTL8211E PHY in RGMII mode, with a GPIO enabling the regulator for I/O signalling power supplies. The PHY's main power supply is enabled by the main 5V power supply. Add the regulator and PHY nodes, and override the PHY phandle under the EMAC node, so that the EMAC works properly on this board.
