Hook up drm_bridge support in the omapdrm driver. Despite the recent extensive preparation work, this is a rather intrusive change, as the management of outputs needs to be adapted through the driver to handle both omap_dss_device and drm_bridge. Connector creation is skipped when using a drm_bridge, as the bridge creates the connector internally. This creates issues with systems that split connector operations (such as modes retrieval and hot-plug detection) across different bridges. These systems can't be supported using drm_bridge for now (their support through the omap_dss_device infrastructure is not affected), this will be fixed in subsequent changes.
