[PATCH 3/3 net-next] net: mdio: mscc-miim: Use devm_of_mdiobus_register()

Use devm_of_mdiobus_register() instead of hand writing it.
This saves some lines of code.

The remove function can be removed completely and the
platform_set_drvdata() call at the end of the probe is now also useless and
can be removed as-well.
