ALSA: msnd: prepare system sleep support
System suspend cannot work for msnd today because the PCM trigger
paths reject SNDRV_PCM_TRIGGER_SUSPEND, and the driver has only
refcounted IRQ helpers.
Add the small helpers needed by the PM callbacks and restore master
volume from the cached ALSA mixer state when the DSP is
reinitialized.
