When a sound capture/playback is terminated while a playback/capture
is running, power_vag_event() will clear SGTL5000_CHIP_ANA_POWER in
the SND_SOC_DAPM_PRE_PMD event, thus muting the respective other
channel.
Don't clear SGTL5000_CHIP_ANA_POWER when both DAC and ADC are active
to prevent this.

No need to hold on to the `codec' pointer. We can use the `dsp'
pointer and grab all the information we need from there. This
makes the parameters for the functions a bit more sane and idiomatic.

Generally, S/PDIF supports 20bit and optional 24bit samples. Thus add these
two formats for the dummy codec drivers.
If one S/PDIF controller has its own limitation, its CPU DAI driver should
set the supported format by its own circumstance, since the soc-pcm driver
will use the intersection of cpu_dai's formats and codec_dai's formats.

Depending on the mclk (or crystal) selected, the wm8731 codec have some
constraints on its data sampling rates:
e.g. with a 12.288MHz or 18.432MHz crystal, the authorized rates are
8KHz, 32KHz, 48KHz and 96KHz.

For some reason, the DAC/ADCs are not being powered up when I try and
use the UDA1341 driver; this used to work. Looking back in the git
history, I don't see anything obvious which would cause this
regression.
However, from dumping the register writes, it seems that the codec is
powered down, and nothing calls set_bias_level to wake the codec up.
Moreover, this driver hasn't had DAPM support added to it, which
prevents platform drivers from taking advantage of DAPMs facilities.
So, let's add DAPM support to the driver.
As we move the power control for the DAC/ADC into DAPM, we no longer
need it in set_bias_level() - this function just becomes a way to
manipulate the power control and sync the register cache with the
hardware at the appropriate point.

The adau1701 driver was removed from SND_SOC_ALL_CODECS in commit commit ee8c7e9
("ASoC: Remove adau1701 from SND_SOC_ALL_CODECS due to Sigma dependency") due
to the dependency on the SigmaDSP firmware loader which was only available on a
limited set of platforms. This was fixed quite some time ago in commit 40216ce7
("ASoC: Move SigmaDSP firmware loader to ASoC") though, so we can add the driver
back again to SND_SOC_ALL_CODECS.

Currently after playing any audio file, we get the following error message:
$ aplay clarinet.wav
Playing WAVE 'clarinet.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ wm8962 0-001a: Unsupported sysclk ratio 544
This error message appears about 5 seconds after the audio playback has
finished.
Quoting Mark Brown [1]:
"The issue here is triggered by the machine
switching from the FLL to direct MCLK usage where the MCLK isn't
generating a useful ratio.
I suspect we should just kill the configure_bclk() in set_sysclk(), that
one isn't safe as we can't reconfigure a live SYSCLK and it's probably
the one that generates your warnings."
Confirmed that the "Unsupported sysclk ratio" error message comes from
wm8962_set_dai_sysclk(), so get rid of wm8962_configure_bclk() inside this
function.
