I'm not sure it is a good idea to completely take over phydev->priv
like this, in what is just helper code. What if the PHY driver needs
memory of its own? There are a few examples of this already in other
PHY drivers. Could a KR PHY contain a temperature sensor? Could it
contain statistics counters which need accumulating?
