Rework fbdev probing to support fbdev_probe in struct drm_driver and remove the old fb_probe callback. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. 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.
