drm/nouveau/disp: Silence DCB warnings.
Most of these errors seem to be WFD related. Official documentation says dcb type 8 is reserved. It's probably used for WFD. Silence the warning in either case. Connector type 70 is stated to be a virtual connector for WiFi display. Since we know this, don't warn that we don't.
