   Creates an Codec97 component.  An struct snd_ac97 instance is newly
   allocated and initialized from the template.  The codec
   is then initialized by the standard procedure.
   </p><p>

   The template must include the codec number (num) and address (addr),
   and the private data (private_data).
   </p><p>

   The ac97 instance is registered as a low-level device, so you don't
   have to release it manually.
