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. The exynos-drm driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely.
