This property is implemented by stmmac and documented in the DT bindings. stmmac has not been updated to use Ethernet PHY nodes.
Removing this property will not affect the function of the driver. The driver probes its MDIO bus and selects the lowest available address if not specified.

Used as specified in stmmac DT bindings.
