net: rework fsl_pq_mdio driver to use of_mdio infrastructure
This patch simplifies the driver by making use of more common code. Tested on Freescale MPC8349emitxgp eval board Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
