Subject: [PATCH] drm/msm/dsi: Set panel orientation when directly connected

Set the panel orientation in drm when the panel is directly connected,
i.e. we're not using an external bridge. The external bridge case is
already handled by the panel bridge code, so we only update the path we
take when the panel is directly connected/internal. This silences a
warning splat coming from __drm_mode_object_add() on Wormdingler boards.

This relies on commit 5e41b01a7808 ("drm/panel: Add an API to allow drm
to set orientation from panel") which is in drm-misc
