[PATCH v3 16/33] drm/mediatek: mtk_hdmi: Move plugged_cb/codec_dev setting to new function

[AngeloGioacchino Del Regno]

In preparation for splitting common bits of this driver, move the
mutex-protected cable plugged callback and codec device setting
to a new function called mtk_hdmi_audio_set_plugged_cb().
