Subject: [PATCH 1/5] ASoC: fsl_micfil: explicitly clear software reset bit
SRES is self-cleared bit, but REG_MICFIL_CTRL1 is defined as
non volatile register, it still remain in regmap cache after set,
then every update of REG_MICFIL_CTRL1, software reset happens.
to avoid this, clear it explicitly.

Subject: [PATCH 2/5] ASoC: fsl_micfil: explicitly clear CHnF flags
There may be failure when start 1 channel recording after
8 channels recording. The reason is that the CHnF
flags are not cleared successfully by software reset.
This issue is triggerred by the change of clearing
software reset bit.
CHnF flags are write 1 clear bits. Clear them by force
write.

Subject: [PATCH 3/5] ASoC: ops: Fix bounds check for _sx controls
For _sx controls the semantics of the max field is not the usual one, max
is the number of steps rather than the maximum value. This means that our
check in snd_soc_put_volsw_sx() needs to just check against the maximum
value.

Subject: [PATCH 4/5] ASoC: ops: Check bounds for second channel in
snd_soc_put_volsw_sx()
The bounds checks in snd_soc_put_volsw_sx() are only being applied to the
first channel, meaning it is possible to write out of bounds values to the
second channel in stereo controls. Add appropriate checks.
