I didn't follow all of the earlier discussions around this, but it seems
to me like data-enable polarity and the pixel data edge flags are
properties of the interface rather than the video mode.

struct drm_display_mode represents the video timings and I'm not sure if
it's a good idea to extend it with this type of information.

Maybe we need to add a separate type of device to store these parameters
(much like we've done for MIPI DSI devices).
