ASoC: msm: qdsp6v2: Fix offload gapless transition

Use smaller fragment sizes at DSP interface than at
user space interface.
This allows to write earlier to the DSP without waiting for
a full user space fragement in case of underrun or gapless
transition.

[satyak@codeaurora.org: allow runtime fragment sizes which
 are not multiples of dsp fragment sizes for direct pcm cases.
 Also fix linker error during compilation for 32 bit architectures
 using do_div() for division]
