The DT bindings for the OMAP DSS allow assigning numerical IDs to display outputs through display entries in the alias node. The driver uses this information to sort pipelines according to the order specified in DT, making it possible for a system to give a priority order to outputs. Retrieval of the alias ID is done when initializing display dss devices. That code will be removed when moving to drm_bridge and drm_panel. Move retrieval of the alias ID to display pipeline connection time and store it in the pipeline structure instead to keep the feature.
