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.
