Previously, we couldn't use hw_params() and hw_free() to open and close FLL
becuase there might be a race between two simmultaneous substreams so the
FLL configuration would be changed and accordingly mulfunction. Also it
wouldn't make sense for bypass path feature
SPDIF can derive a TX clock for playback from one of its clock sources --
spdif root clock to match its supporting sample rates. So this patch set
the spdif root clock's parent to pll3_pfd3_454m since the pll3_pfd3_454m
can approximately meet its sample rate requirement.

DPCM needs extra dapm routes in the machine driver to route audio
between Front-End and Back-End. In order to differ the stream names
in the route map from CODECs, we here add specific stream names to
SAI driver so that we can implement ASRC via DPCM to it.

This patch adds support for the Cirrus Logic CS42888 Audio CODEC that
has four 24-bit A/D and eight 24-bit D/A converters.
[ CS42888 supports both I2C and SPI control ports. As initial patch,
this patch only adds the support for I2C. ]

v3:
* Refined
tical. Otherwise, it'll
make one of dai work in an incorrect mode.
Thus this patch fixes it by overwriting the DAIFMT_MASTER bit of cpu_dai->fmt
with the one of codec_dai->fmt since we defined DAIFMT_MASTER basing on CODEC
at the first place.

The regular state before we execute SNDRV_PCM_TRIGGER_SUSPEND should be
SNDRV_PCM_TRIGGER_START, not SNDRV_PCM_TRIGGER_STOP. Thus fix it.
