ASoC: qcom: qdsp6: q6asm-dai: set 10 ms period and buffer alignment.

commit 81c53b52de21b8d5a3de55ebd06b6bf188bf7efd upstream.

DSP expects the periods to be aligned to fragment sizes, currently
setting up to hw constriants on periods bytes is not going to work
correctly as we can endup with periods sizes aligned to 32 bytes however
not aligned to fragment size.

Update the constriants to use fragment size, and also set at step of
10ms for period size to accommodate DSP requirements of 10ms latency.
