ASoC: pcm_dmaengine: Extract snd_dmaengine_pcm_refine_runtime_hwparams

Browse source

When set the runtime hardware parameters, we may need to query
the capability of DMA to complete the parameters.

This patch is to Extract this operation from
dmaengine_pcm_set_runtime_hwparams function to a separate function
snd_dmaengine_pcm_refine_runtime_hwparams, that other components
which need this feature can call this function.
