drm: gm12u320: Some minor cleanups

3 small cleanups:

1) Drop unused DRIVER_PATCHLEVEL
2) We do not set mode_config.preferred_depth, so instead of passing the
   unset mode_config.preferred_depth to drm_fbdev_generic_setup
   simply pass 0
3) Use __maybe_unused instead of #ifdef CONFIG_PM around the suspend /
   resume functions
