drm/cirrus: Run DRM default client setup

Browse Source 
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 cirrus driver requests the same client pixel format as the value
stored in struct drm_mode_config.preferred_depth. The fbdev client
also looks at this value for the default pixel format. Thus remove
the format selection from cirrus.

v5:
- select DRM_CLIENT_SELECTION
