ASoC: fsl_micfil: explicitly clear software reset bit

[ Upstream commit 292709b9 ]

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.
