If a dt mdio entry has been added least assume that we wont
search for phys attached. The DT and of_mdiobus_register already do
this. This stops DSA phys being found and phys created for them, as
this is handled by the DSA driver.
iiuc, this doesn't conflict with the recent rework we are doing
for the mdio/phy platform management.
