[PATCH net-next 2/2] net: mdio-ipq8064: remove _remove function

[Rosen Penev <rosenp@gmail.com>]

Change of_mdiobus_register to devm_mdiobus_register as devm allows
removing the _remove function as well as slightly cleaning up the probe
function.

Regular mdiobus_register is fine here as the platform device's of_node
is used. Removes two variables from _probe.
