ASoC: fsl_micfil: Add DC output remover control
Add support for the DC output remover feature available on i.MX93 and
newer platforms. This allows users to configure the output DC removal
filter with cut-off frequencies of 20Hz, 13.3Hz, 40Hz, or bypass it
entirely.
The control is exposed as an ALSA mixer control and defaults to bypass
mode. It is only available on platforms with the use_verid flag set
(i.MX93+).
