Subject: [PATCH v5 5/5] ASoC: qdsp6: q6apm-dai: fix capture pipeline overruns.

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

Period sizes less than 6k for capture path triggers overruns in the
dsp capture pipeline.

Change the period size and number of periods to value which DSP is happy with.

Fixes: 9b4fe0f1cd79 ("ASoC: qdsp6: audioreach: add q6apm-dai support")
