[PATCH 3/5] usb: dwc3-generic: Relax unsupported dr_mode check

[Jonas Karlman]

When dr_mode is peripheral or otg and U-Boot has not been built with
DM_USB_GADGET support, booting such device may end up with:

  dwc3_glue_bind_common: subnode name: usb@fcc00000
  Error binding driver 'dwc3-generic-wrapper': -6
  Some drivers failed to bind
  initcall sequence 00000000effbca08 failed at call 0000000000a217c8 (err=-6)
  ### ERROR ### Please RESET the board ###

Instead fail gracfully with ENODEV to allow board continue booting.

  dwc3_glue_bind_common: subnode name: usb@fcc00000
  dwc3_glue_bind_common: unsupported dr_mode
