Subject: [PATCH v2 4/5] ASoC: qdsp6: q6apm-dai: set correct period size

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

For some reason we ended up with a period size which is less than 1ms,
DSP does not support such a small fragment size. Adjust this to be in
the range of 16ms to 32ms.
