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.

Support three different use cases with rockchip_max98090 driver:

- max98090 only: Current usage, where HDMI link is missing. - HDMI only: Needed use case for veyron_mickey board. - max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc.

Note that we keep max98090 only usage for backward compatibility.

From devicetree, different compatible string can be passed to configure

the usage.
