Aren't these messages backward?  The hardware is set to device mode,
CONFIG_USB_DWC3_HOST means, "Support only host mode," so it should
fail because Barebox does not support device mode.

Maybe something like: "Barebox built without support for DWC3 USB
device mode (USB_DWC_HOST).\n"  Let the person know what variable to
search for in the config menu to change it.
