net: dsa: ocelot: seville: utilize of_mdiobus_register

BugLink: https://bugs.launchpad.net/bugs/1964361
[ Upstream commit 5186c4a05b9713138b762a49467a8ab9753cdb36 ]

Switch seville to use of_mdiobus_register(bus, NULL) instead of just
mdiobus_register. This code is about to be pulled into a separate module
that can optionally define ports by the device_node.
