So there were two ways to look at this, one was that could check here
that ds->pd is assigned and port->name is assigned, which means that
platform data has to provide valid port name. We can also eliminate this
check entirely because we now support NULL names just fines.

Humm, that could be done, maybe for simplicity we can just let
net/dsa/dsa2.c assign names either based on what platform data provided,
or by falling back to eth%d.

Thanks!
