[PATCH 24/86] drm/logicvc: Run DRM default client setup

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 logicvc driver specifies a preferred color mode from the value
in struct drm_mode_config. Use it to select the default format.
