Preliminary step in making snd_hda_codec_device_init() the only constructor for struct hda_codec instances. To do that, no struct may wrap struct hda_codec as its base type.
To drop hdac_to_hda_priv(), hdac_hda_dev_probe() now skips dev_set_drvdata(). Driver private data will be assigned by owning bus drivers instead.
