[PATCH v2 20/60] drm/omap: dss: Add functions to connect and disconnect devices

The omap_dss_device objects model display components and are connected at runtime to create display pipelines. The connect and disconnect operations implemented by each component contain lots of duplicate code. As a first step towards fixing this, create new functions to wrap the direct calls to those operations and use them.
