[PATCH net-next 05/11] net: fsl_pq_mdio: return directly in probe

[Rosen Penev <rosenp@gmail.com>]

Instead of generating two errors in probe, just return directly to
generate one.

mdiobus_register was switched away from the of_ variant as no children
are being used.

No more need for a _remove function.
