[PATCH net-next 8/8] ARM: orion: Register DSA switch as a MDIO device

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.
