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

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.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.
