Use the newly added fields in omap_video_timings(hsync, vsync and data_enable logic levels and data, hsync and vsync latching related info) to configure/retrieve corresponding drm mode flags in drm_display_mode. Out of the new fields, hsync_level and vsync_level can be mapped to the drm mode flags DRM_MODE_FLAG_PHSYNC, DRM_MODE_FLAG_NHSYNC, DRM_MODE_FLAG_PVSYNC and DRM_MODE_FLAG_NVSYNC When converting drm mode to omap_video_timings, the fields which don't have an equivalent parameter in drm mode are set to the default values.
