Subject: [PATCH] usb: dwc3: Fix non-usb3 configurations
Missing nodes may also be signaled via -ENODATA. We need to check for
that to prevent failing in non-usb3 setups.
Furthermore, dev.phy must be NULL'ed in case usb3-phy was not found.
Fixes: 142d50fbce7c ("usb: dwc3: Add support for usb3-phy PHY configuration")
