If the PHY isn't specified in the DT, -ENODATA means it should be skipped, handle it like -ENOENT.
With that, devices without USB3 supported can have USB working (Odroid-HC4).
Shouldn't you rather specify NOP PHY in the DT ?
Who NOP I would have no idea if the port is disabled or used. The PHY control is mixed between the actual PHY driver and the DWC3/DWC2 glue, so the bindings were designed to make some PHYs phandle optionals if unused.
