ASoC: fsl_micfil: Fix event generation in micfil_quality_set()

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

Add a suitable check in the function before updating the quality variable.

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