We currently have videomode_from_timing(), which takes one display_timing entry from display_timings. To make it easier to use display_timing without display_timings, this patch renames videomode_from_timing() to videomode_from_timings(), and adds a new videomode_from_timing() which just converts a given display_timing to videomode.
