drm/bridge/panel: hold a reference to the wrapped panel
drm_panel_bridge_add_typed() stores a pointer to the drm_panel it
wraps, but never acquires a reference to it. If the panel device
goes away while a panel_bridge still exists, the dangling pointer can
be dereferenced through panel_bridge->panel.
Acquire a reference in drm_panel_bridge_add_typed() with drm_panel_get()
and release it in each teardown path.
