Notes:
    This was originally part of the series adding the MDIO driver[1] however
    the mips specific part wasn't picked up for net-next so I've rolled it
    into this series of changes for linux-mips.
    
    This is needed to comply with the updated bindings. It could
    possibly be split to add the ports then the PHYs. Technically the
    ports are the required property that dtbs_check will complain about
    but it didn't seem worth separating out the PHYs.
