[PATCHv5][ 1/5] fbdev: Add the lacking FB_SYNC_* for matching the DISPLAY_FLAGS_*

[Denis Carikli <denis-fO0SIAKYzcbQT0dZR+AlfA@public.gmane.org>]

Without that fix, drivers using the fb_videomode_from_videomode
  function will not be able to get certain information because
  some DISPLAY_FLAGS_* have no corresponding FB_SYNC_*.
