powerpc/mpc5200: Remove obsolete code from mpc5200 MDIO driver
As this driver polls for a complete MDIO transaction, there is no need to enable interrupts for it. Furthermore, make both checks for freeing MDIO-bus irqs consistent. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
