The schemas for MDIO bus nodes range from missing to duplicating
everything in mdio.yaml. The MDIO bus node schemas only need to
reference mdio.yaml, define any binding specific properties, and define
'unevaluatedProperties: false'. This ensures that MDIO nodes only
contain defined properties. With this, any duplicated properties can
be removed.

With the legacy mapping the reg corresponding to the internal
