drm/stm: Run DRM default client setup

Call drm_client_setup_with-fourcc() 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.

v5:
- select DRM_CLIENT_SELECTION
v4:
- remove duplicated S-o-b tag (Gerd)
v2:
- use drm_client_setup_with_fourcc()
