Currentlly, for HDA jack, we will create jack kctl before calling snd_jack_new(). In our new design, this kctl should belong to the jack, so we add a param(struct snd_jack_kctl *) to pass the kctl, then we can add the kctl to jack during jack creating. This make our design more compatible with existing HDA jack kctl.
