Subject: [PATCH] usb: dwc3-meson-g12a: skip phy on -ENODATA aswell
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).
Fixes: adb049abf7 ("usb: dwc3: Add Meson G12A USB Glue")
