Jack is created based on pcm.
Apply the acomp jack rule to dyn_pcm_assign. For dyn_pcm_assign: Driver does not use hda_jack. It operates snd_jack directly. snd_jack pointer will be stored in spec->pcm.jack instead of the current spec->acomp_jack. When pcm is assigned to pin, jack will be assigned to pin automatically. For !dyn_pcm_assign: Driver continues using hda_jack for less impact on the old cases. Pcm is statically assigned to pin. So is jack. spec->pcm.jack saves the snd_jack pointer created in hda_jack.
