realtek: mdio: setup topology from control structure

Browse Source 
The topology setup is bus independent and can be derived completely
from the control structure. Adapt the call parameters accordingly.

The call location is quite confusing at the moment. Being no longer
dependent from the bus call it where it makes most sense. This is
directly after the mapping setup in rtmdio_map_ports(). Doing other
bus dependent setup between these two functions is not needed
any longer.
