ASoC: fsl_micfil: Fix event generation in micfil_put_dc_remover_state()

ALSA controls should return 1 if the value in the control changed but the
control put operation micfil_put_dc_remover_state() only returns 0 or a
negative error code, causing ALSA to not generate any change events.

return the value of snd_soc_component_update_bits() directly, as it has
the capability of return check status of changed or not.

Also enable pm runtime before calling the function
snd_soc_component_update_bits() to make the regmap cache data align with
the value in hardware.
