[PATCH 09/13] ASoC: Intel: avs: drop SNDRV_PCM_RATE_KNOT

[Jerome Brunet]

The custom rate constraint list was necessary to support 12kHz, 24kHz and
128kHz. These rates are now available through SNDRV_PCM_RATE_12000,
SNDRV_PCM_RATE_24000 and SNDRV_PCM_RATE_128000.

Use them and drop the custom rate constraint rule.
