[PATCH] ALSA: ti: Use pcm_for_each_format() macro for PCM format iteration

[Min-Hua Chen <minhuadotchen@xxxxxxxxx>]

Use pcm_for_each_format for the PCM format iteration and fix the
following sparse warnings.

sound/soc/ti/davinci-mcasp.c:1336:26: sparse: warning: restricted snd_pcm_format_t degrades to integer
sound/soc/ti/davinci-mcasp.c:1358:26: sparse: warning: restricted snd_pcm_format_t degrades to integer
sound/soc/ti/davinci-mcasp.c:1438:26: sparse: warning: restricted snd_pcm_format_t degrades to integer

No functional changes.
