[PATCH] usb: dwc3: Fix support for usb3-phy PHY configuration

[Marek Vasut]

The dev_read_stringlist_search() in generic_phy_get_by_name()
returns -ENODATA in case of missing "phy-names", which is the
case on everything except ZynqMP. Handle this -ENODATA instead
of failing outright, which fixes the glue on everything else.
