Add the required DT parts to enable Ethernet (dwmac-sun8i driver) on the Orange Pi Prime board. It uses an external Realtek RTL8211E PHY connected via RGMII to provide GbE network. This includes the regulator (which is controlled by a GPIO pin) and the actual Ethernet MAC node, referring the RGMII pins of the device.
