[PATCH v2 3/3] drm/panel: lg-sw43408: use devm_drm_panel_add()

[Myeonghun Pak]

Replace drm_panel_add()/drm_panel_remove() with devm_drm_panel_add()
now that drm-misc-next provides it. This keeps panel deregistration tied
to the device lifetime and removes the manual cleanup from the remove
callback.
