[PATCH 2/2] ASoC: fsl_micfil: Differentiate register access permission for platforms

[Shengjiu Wang]

On i.MX9x platforms, the REG_MICFIL_FSYNC_CTRL, REG_MICFIL_VERID,
REG_MICFIL_PARAM are added, but they are not existed on i.MX8x
platforms.

Use the existed micfil->soc->use_verid to distinguish the access
permission for these platforms.
