MLK-15028: ASoC: codecs: wm8960: Remove bitclk relax condition

Using a higher bitclk then expected doesn't always work.
Here is an example:

aplay -Dhw:0,0 -d 5 -r 48000 -f S24_LE -c 2 audio48k24b2c.wav

In this case, the required bitclk is 48000 * 24 * 2 = 2304000
but the closest bitclk that can be derived is 3072000.

Now, for format S24_LE, SAI will use slot_width = 24, but since
the clock is faster than expected, it will start to send bytes
from the next channel so the sound will be corrupted.

Thus, remove bitclk relaxation condition which was added mostly
for supporting S20_3LE format which was removed from SAI in
commit 739e6d654b5c0a ("MLK-14870: ASoC: fsl_sai: Remove support
for S20_3LE").
