Fix PHY Lib support for gianfar and ucc_geth
The PHY Lib now uses mutexes instead of spin_locks. ucc_geth and gianfar both grab the locks in their mdio_reset functions, so they need to use mutex_(un)lock instead. This was not caught until someone tested it on an SMP system. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
