Fix sparse warning:
sound/soc/fsl/fsl_asrc.c:1177:60: sparse: warning: incorrect type in argument 3 (different base types)
sound/soc/fsl/fsl_asrc.c:1177:60: sparse:    expected unsigned int [usertype] *out_value
sound/soc/fsl/fsl_asrc.c:1177:60: sparse:    got restricted snd_pcm_format_t *
sound/soc/fsl/fsl_asrc.c:1200:47: sparse: warning: restricted snd_pcm_format_t degrades to integer

Fixes: 4520af41fd21 ("ASoC: fsl_asrc: Support new property fsl,asrc-format")
