Merge series "ASoC: fsl_sai: update the register list" from Shengjiu Wang <shengjiu.wang@nxp.com>: 

As sai ip is upgraded, so update sai register list.

Shengjiu Wang (3):
  ASoC: fsl_sai: Add new added registers and new bit definition
  ASoC: fsl_sai: Add fsl_sai_check_version function
  ASoC: fsl_sai: Set MCLK input or output direction

changes in v2:
- update commit message for first commit
- Add acked-by Nicolin
