Utilize the ability to pass board specific MDIO bus information towards a particular MDIO device thus allowing us to provide the per-port switch layout to the Marvell 88E6XXX switch driver. Since we would end-up with conflicting registration paths, do not register the "dsa" platform device anymore.
