MLK-15101: ASoC: imx-wm8962: Use a lower FLL output rate for S20_3LE and S24_LE formats
Using a lower FLL out frequency seems to fix the sound distortion we hear
during playback of the second audio file from the command:
aplay -Dhw:0 -d 1 audio96k16b2c.wav audio96k24b2c.wav
Because the new frequency is half of the old one the existing BLCK compute
formula from wm8962 codec driver is still correct, it can derive the new
FLL output frequency.
