Subject: [RFC PATCH 4/4] drm: panel-lvds: Introduce dual-link panels

Add a new compatible, "panel-dual-lvds".

Dual-link LVDS interfaces have 2 links, with even pixels traveling on
one link, and odd pixels on the other. These panels are also generic in
nature, with no documented constraints, much like their single-link
counterparts, "panel-lvds".
