Since only USB device controller is integrated, there are warnings on terminal.
The change is to enable only device role and thus eliminate the warnings.
Below is the error message shown on terminal.

[   89.421700] xhci-hcd xhci-hcd.3.auto: xHCI Host Controller
[   89.421844] xhci-hcd xhci-hcd.3.auto: new USB bus registered, assigned
