Drop the limitation of a single PCS in pcs-handle property. Multiple PCS can be defined for an ethrnet-controller node to support various PHY interface mode type. It's very common for SoCs to have a 2 or more dedicated PCS for Base-X (for example SGMII, 1000base-x, 2500base-x, ...) and Base-R (for example USXGMII,10base-r, ...) with the MAC selecting one of the other based on the attached PHY.
