MLK-10048-4: ASoC: fsl_asrc: fix dma task timeout issue when use 3 instance
Merged from 49108fcf7b79ed77d34be33b53a3964b2ac27204
1. Watermark level in sdma use byte as its unit. but asrc driver use
word, there is mismatch between them. Here fix this issue and sdma can
work more efficiency.
2. Enlarge the larst_period_size, when use small size, for some case,
the dma task will timeout, because sdma has no much data for output.
