ASoC: cs35l34: drop useless rate contraint
The cs35l34 adds a useless rate constraint on startup.
It does not set SNDRV_PCM_RATE_KNOT and the rates set are already a subset
of the ones provided in the constraint list, so it is a no-op.
>From the rest of the code, it is likely HW supports more than the 32, 44.1
and 48kHz listed in CS35L34_RATES but there is no way to know for sure
without proper documentation.
Keep the driver as it is for now and just drop the useless constraint.
