drm/mediatek: support HDMI jack status reporting
1.
Provides a callback (i.e. mtk_hdmi_audio_hook_plugged_cb) to hdmi-codec.
When ASoC machine driver calls hdmi_codec_set_jack_detect(), the
callback will be invoked to save plugged_cb and codec_dev parameters.
+---------+ set_jack_ +------------+ plugged_cb +----------+
| machine | ----------> | hdmi-codec | ----------> | mtk-hdmi |
+---------+ detect() +------------+ codec_dev +----------+
2.
When there is any jack status changes, mtk-hdmi will call the
plugged_cb() to notify hdmi-codec. And then hdmi-codec will call
snd_soc_jack_report().
+----------+ plugged_cb +------------+
| mtk-hdmi | ----------> | hdmi-codec | -> snd_soc_jack_report()
+----------+ codec_dev +------------+
