[PATCH 6/7] drm/vc4: dsi: stop using deprecated drmm_of_get_bridge()

[Luca Ceresoli]

devm_drm_of_get_bridge() is deprecated, switch to
of_drm_get_bridge_by_endpoint(). As of_drm_get_bridge_by_endpoint() returns
a refcounted bridge, ensure it is put by using bridge.next_bridge.

drm_panel.h becomes unused, drop the include.
