Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.
The dcss driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.
