This is not quite correct. For marvell,mv88e6085 and marvell,mv88e6250
there is one MDIO bus, which can be used both internally and
externally.

For marvell,mv88e6190, there are two MDIO buses. This one is used only
internally, and 'mdio-external' is connected to pins for external use.

Also, its not used to access switch ports. It is used to access PHYs
which can connected to switch ports.
