Add a property for associating PCS devices with ethernet controllers. Because PCS has no generic analogue like PHY, I have left off the -handle suffix.For PHYs, we used to have phy and phy-device as property names, but the modern name is "phy-handle". I think we should do the same here, so I would suggest using "pcs-handle".
On 1G and up ethernet, we have 2 PHYs. There's the external (typically) ethernet PHY which is what the above properties are for. Then there's the on-chip serdes PHY similar to SATA, PCIe, etc. which includes the PCS part. For this part, we should use the generic PHY binding. I think we already have bindings doing that. Rob
