Enable the necessary nodes to make this port functional. Enable combphy2 with rockchip,sgmii-mac-sel = <0> to route the SGMII interface to GMAC0. Enable the xpcs node and its port 0 sub-node, referencing combphy2 as the SerDes PHY. Add the mdio0 node with the YT8521SC PHY at address 3, including its reset GPIO and LED configuration. Also add LED configuration for the existing RGMII PHY on mdio1 for consistency.
