[PATCH 15/22] drm: Add the lacking DRM_MODE_FLAG_* for matching the DISPLAY_FLAGS_*

[denis@eukrea.com (Denis Carikli)]

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