video: add of helper for display timings/videomode
This adds support for reading display timings from DT into a struct display_timings. The of_display_timing implementation supports multiple subnodes. All children are read into an array, that can be queried. If no native mode is specified, the first subnode will be used. For cases where the graphics driver knows there can be only one mode description or where the driver only supports one mode, a helper function of_get_videomode is added, that gets a struct videomode from DT.
