Drivers might need to update DRM connector in the drm_bridge_funcs.hpd_notify callback (e.g. it might be necessary to update EDID before setting ELD). Add corresponding argument to the callback.

While LT9611UXC is a DSI-to-HDMI bridge, it implements all HDMI-related functions internally, in the firmware, thus it doesn't make sense to implement DRM_BRIDGE_OP_HDMI. However it is possible to implement DRM_BRIDGE_OP_HDMI_AUDIO, streamlining HDMI audio plumbing (which includes plugged notifications and ELD handling). Implement corresponding callbacks and trigger EDID read / drm_connector_hdmi_audio_plugged_notify() from the hpd_notify callback.
