Merge branch 'topic/pcm-device-suspend' into for-next 

Pull the PCM suspend improvement / cleanup.
This moves the most of snd_pcm_suspend*() calls into PCM's own device
PM ops.  There should be no change from the functionality POV.

As shown in the above, it's better to save registers after suspending
the PCM operations via :c:func:`snd_pcm_suspend_all()` or
:c:func:`snd_pcm_suspend()`. It means that the PCM streams are
already stopped when the register snapshot is taken. But, remember that
you don't have to restart the PCM stream in the resume callback. It'll
be restarted via trigger call with ``SNDRV_PCM_TRIGGER_RESUME`` when
necessary.
Note that, at the time this callback gets called, the PCM stream has
been already suspended via its own PM ops calling
:c:func:`snd_pcm_suspend_all()` internally.
OK, we have all callbacks now. Let's set them up. In the initialization
of the card, make sure that you can get the chip data from the card
