The current position update is not precise enough for PulseAudio to
work reliably with the timer-based scheduling on Baytrail,
Cherrytrail, Broadwell.
Disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that
the position is only reliable and updated during period_elapsed
events.
This will be reverted when the firmware provides a more accurate
position for those platforms.
