net: ethoc: Account for duplex changes 

ethoc_mdio_poll() which is our PHYLIB adjust_link callback does nothing,
we should at least react to duplex changes and change MODER accordingly.
Speed changes is not a problem, since the OpenCores Ethernet core seems
to be reacting okay without us telling it.
