MLK-22598: ASoC: fsl_micfil: Reset channel output data Flag
With the case below, there is issue that after recording with
8 channels, the recording of 1 channel will fail.
arecord -Dhw:2,0 -r 32000 -f S16_LE -c 8 -d 5 -t raw /tmp/test1.pcm
arecord -Dhw:2,0 -r 32000 -f S16_LE -c 1 -d 5 -t raw /tmp/test2.pcm
arecord: pcm_read:2143: read error: Input/output error
The reason is that we need to reset channel output data Flag before
we start the recording
