Sitong Chen 60fafe3440 ASoC: msm: qdsp6v2: write all periods to DSP on playback trigger
In mmap mode, when playback is triggered, send as much as periods
to DSP.

In previous implementation, only 1 period be sent to DSP at trigger
time, it's consumed in DSP and then send back a write-done event,
which will be captured and trigger another write action in the
event_handler.
The problem is, any jitter in the event transmission will result
in a delay on the next write, and a gap in the output is noticeable.
A multiple-periods queue in DSP can filter out such a jitter to
avoid impact to the output.
