drm/omap: hdmi4: Register a drm_bridge for EDID read
In order to integrate with a chain of drm_bridge, the internal HDMI4
encoder has to expose the EDID read operation through the drm_bridge
API. Register a bridge at initialisation time to do so.
For the time being make the next bridge in the chain optional as the
HDMI output is still based on omap_dss_device. The create_connector
argument to the bridge attach function is also ignored for the same
reason. This will be changed later when removing the related
omapdrm-specific display drivers.
