Define snd_ak4114_suspend() and snd_ak4114_resume() functions to handle PM properly, stopping and restarting the work at PM. Currently only ice1712/juli.c deals with the PM and ak4114, so fix the calls there appropriately.
The same PM functions are defined in ak4113.c, too, although they aren't currently called yet (ice1712/quartet.c may be enhanced to support PM later).
