Another issue is that there is only one global soc_ac97_ops in the
whole system. In case there are two different ac97 ports, how to
handle?
Even though the two ac97 ports are same, how could CPU DAI related
private data can be given to snd_ac97 to let it use that data to
execute different operations? It seems snd_ac97 is only attached to
codec.
