ASoC: SOF: Intel: Introduce HDA codec init and exit routines
[ Upstream commit 829c67319806009abfe3b0b82b3b8b153a2c5e32 ]
Preliminary step in making snd_hda_codec_device_init() the only
constructor for struct hda_codec instances. To do that, existing usage
of hdac_ext equivalents has to be dropped.
