MLK-12165: ASoC: fsl: imx-cs42888: remove 32k and 64k support
Revert "MLK-11623 ASoC: imx-cs42888: add 32k and 64k sample rate support"
This reverts commit 314a01f40599134086480ef3c5e89a54aeedbf1f.
In Async mode, record and playback use different samplerate, one is 32k,
another is 48kHz, there will be issue "unsupported sysclk ratio".
example case is
arecord -Dhw:0,1 -f S16_LE -r 32000 -c 2 | aplay -f S16_LE -r 32000 -c 2
