[PATCH] ASoC: fsl_asrc: use internal measured ratio for non-ideal ratio mode

[Shengjiu Wang]

When USRC=0, there is underrun issue for the non-ideal ratio mode;
according to the reference mannual, the internal measured ratio can be
used with USRC=1 and IDRC=0.

Fixes: d0250cf4f2ab ("ASoC: fsl_asrc: Add an option to select internal ratio 
mode")
