[media] omap3isp: Move media_entity_cleanup() from unregister() to cl…

…eanup() The media_entity_cleanup() function belong to the module cleanup handlers, not the entity registration handlers. Move it there. Create a omap3isp_video_cleanup() function to cleanup the video node entity, and call it from the module cleanup handlers. Rename omap3isp_stat_free() to omap3isp_stat_cleanup().
