topology: imx8: Use s32le format for wm8960 codec 

wm8960 codec drivers the master clock and for s24le we cannot easily
derive the bitclk.

So, switch to s32le. SAI supports s32le format. The initial s23le was
added because topology was based on sof-imx8qxp-cs42888.m4 which uses
ESAI and that's limited to s24le.
