This is a deprecated property for stmmac, just use the correct PHY
address and use a phy-handle property to connect to it, along with a
proper mdio subnode to indicate it is connecting to the stmmac MDIO bus.

These are all PHY properties, and the driver and binding now recommend
using them as such, can you move that to the PHY node instead?
