[REBASED on main (r3branch)from r2-stable branch]audio:disable the clocks in stream event callback

BZ: 17975

MSIC PLL and external PLLIN clock sources are disabled
during vaud bias off event.  However vaud bias will continue
to be active when headset is connected.  This will make the
PLLs to active even during no audio playback.

Disable the PLLs after DAPM power down sequence completes.
This will save some mW of power.
