drm/omap: Report HDMI hotplug events to the ASoC HDMI codec
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.
