net: altera-tse: Don't use netdev name for the PCS mdio bus

The PCS mdio bus must be created before registering the net_device. To
do that, we musn't depend on the netdev name to create the mdio bus
name. Let's use the device's name instead.

Note that this changes the bus name in /sys/bus/mdiobus
