usb: dwc3: gadget: Revert "set gadgets parent to the right controller"

The commit c6e23b8 ("usb: dwc3: gadget: set gadgets parent to the right
controller") changed the device for the UDC and broke the user space scripts
that instantiate the USB gadget(s) via ConfigFS.

Revert it for now until the better solution will be proposed.
