I don't think this makes sense, there are perfectly legit reasons why a
switch driver may have something to do with the PHY device attached to
its per-port network interface, we should definitively keep that around,
unless you think we should be accessing the PHY within the switch
drivers by doing:

struct phy_device *phydev = ds->ports[port].netdev->phydev?
