drm: bridge: dw-hdmi: Report connector status using callback
Allow codec driver register callback function for plug event. The callback registration flow: dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec dw-hdmi-i2s-audio implements hook_plugged_cb op so codec driver can register the callback. dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device can register the callback. When connector plug/unplug event happens, report this event using the callback. Make sure that audio and drm are using the single source of truth for connector status.
