Enable fixed-mclk feature on imx-swpdm this allows to
have exact divide ratios for clocking configuration
for SAI mclk and bitclk this improves performance for
voice applications.

Set decimation factor to 64 this allows to support all
possible sample rates for SPK0641HT4H-1 on 8mic board
Example: 16khz: BCLK = 16khz * 64 = 1024000 Hz
[ 8000 - 11025] low power mode
[16000 - 64000] performance mode

Use fsl,dataline,dsd channel mask to enable only SAI
datalines available per SAI block; On SAI5 0xf enables
4 datalines on SAI5_RX; Up to 4 channels capture, one
channel per dataline.
