ASoC: qcom: q6apm-dai: add push-pull and watermark event support

Browse source

Wire q6apm-dai to use push-pull shared memory graphs.

For push-pull graphs, configure the circular buffer and position buffer,
register watermark events, and use watermark notifications to report PCM
period elapsed. Skip legacy fragment queueing and ACK handling because the
DSP reads/writes directly from the shared circular buffer.
