Subject: [PATCH v3 3/8] drm/panel: sw43408: Introduce LH546WF1-ED01 panel
 compatible

From: David Heidelberg <david@...t.cz>

The supported panel is LH546WF1-ED01, add compatible and adjust the
struct name to reflect that.

The standalone compatible lg,sw43408 will continue to work, even thou
there are no users yet.
