dmaengine: fsl-edma: correct calculation of 'nbytes' in multi-fifo scenario
commit 9ba17defd9edd87970b701085402bc8ecc3a11d4 upstream.
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.
