Taking into account, whatever MII variation is implemented in the SoC
is always internal (and only MDIO part is multiplexed), can we add
	phy-mode = "internal";
and
	phy-handle = <&internal_ephy>;
right into cv180x.dtsi?

Boards can then enable the corresponding nodes if they wire RJ45 connector,
but I see no way how they could vary the MII connection.
