MLK-15042: ASoC: fsl_asrc: update supported format

The ASRC support 24 bit input width, but for S20_3LE the input width
is 20 bit, asrc will treat it as 24bit, which like a 24bit data shift
4 bit right, the result is the volume is lower than expected.
ASRC can't shift the 20bit data left 4 bit internally, so remove the
S20_3LE in supported list, add S24_3LE in supported list.
