dmaengine: fsl-edma: correct calculation of 'nbytes' in multi-fifo scenario

From: Joy Zou <[email protected]>

The 'nbytes' should be equivalent to burst * width in audio multi-fifo setups. Given that the FIFO width is fixed at 32 bits, adjusts the burst size for multi-fifo configurations to match the slave maxburst in the configuration.
