The OMAP HDMI audio driver currently has no way of reporting HDMI cable hotplug events to ASoC. As a result, user space cannot detect HDMI audio availability through the standard jack mechanism and audio policy managers cannot automatically route audio to or from the HDMI output. Add an optional HPD callback to `omap_hdmi_audio_pdata` and invoke it from the DRM HDMI bridge whenever the connector status changes. The HDMI audio driver registers an ASoC jack and reports `SND_JACK_AVOUT` state changes in response to these notifications. Also fix the disconnect path by taking a runtime PM reference before updating the CEC physical address.
