ASoC: zte: Fix incorrect PCM format bit usages

zx-tdm driver sets the DAI driver definitions with the format bits
wrongly set with SNDRV_PCM_FORMAT_*, instead of SNDRV_PCM_FMTBIT_*.

This patch corrects the definitions.

Spotted by a sparse warning:
  sound/soc/zte/zx-tdm.c:363:35: warning: restricted snd_pcm_format_t degrades to integer
