ASoC: fsl: fsl_qmc_audio: Fix snd_pcm_format_t values handling

Browse source

Running sparse on fsl_qmc_audio (make C=1) raises the following warnings:
 fsl_qmc_audio.c:387:26: warning: restricted snd_pcm_format_t degrades to integer
 fsl_qmc_audio.c:389:59: warning: incorrect type in argument 1 (different base types)
 fsl_qmc_audio.c:389:59:    expected restricted snd_pcm_format_t [usertype] format
 fsl_qmc_audio.c:389:59:    got unsigned int [assigned] i
 fsl_qmc_audio.c:564:26: warning: restricted snd_pcm_format_t degrades to integer
 fsl_qmc_audio.c:569:50: warning: incorrect type in argument 1 (different base types)
 fsl_qmc_audio.c:569:50:    expected restricted snd_pcm_format_t [usertype] format
 fsl_qmc_audio.c:569:50:    got int [assigned] i
 fsl_qmc_audio.c:573:62: warning: incorrect type in argument 1 (different base types)
 fsl_qmc_audio.c:573:62:    expected restricted snd_pcm_format_t [usertype] format
 fsl_qmc_audio.c:573:62:    got int [assigned] i

These warnings are due to snd_pcm_format_t values handling done in the
driver. Some macros and functions exist to handle safely these values.

Use dedicated macros and functions to remove these warnings.
