ASoC: fsl_sai: Add support multi fifo sdma script
With disabling combine mode, the multiple successive
FIFO registers or non successive FIFO registers of SAI module
can work with the sdma multi fifo script.
This patch is to configure the necessary information to
the SDMA engine driver for support multi fifo script.
'words_per_fifo' is the channels for each dataline
'n_fifos_src' and 'n_fifos_dst' are the fifo number
'stride_fifos_src' and 'stride_fifos_dst' are the stride
between enable FIFOs
'maxburst' is the multiply of datalines
