Current snd_soc_runtime_set_dai_fmt() is called after
soc_probe_link_dais(). this means snd_soc_dai_set_fmt() will be
called after soc_new_pcm().
Before appling 1efb53a220b78fdfdbb97b726a2156713e75bdab
(ASoC: simple-card: Remove support for setting differing DAI formats)
simple-card user had (1) snd_soc_dai_set_fmt() -> soc_new_pcm(),
but, after that it is (2) soc_new_pcm() -> snd_soc_dai_set_fmt().
At least rsnd driver is assuming (1) pattern.
This patch move snd_soc_dai_set_fmt() into soc_probe_link_dais()
after the dai_link->init section to solve this issue.

The wm8350 driver is the last driver that still uses the delayed_work field
from the snd_soc_dapm_context struct. Moving this over to the driver's
private data struct will allow us to remove the field from the DAPM context,
which will drastically reduce its size.

The only two users of the suspend_bias_level field were two rather old
drivers which weren't exactly doing things by the book. Those drivers have
been updated and field is now unused and can be removed.

Set the CODEC driver's suspend_bias_off flag rather than manually going to
SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes
the code a bit shorter and cleaner.
Since the ASoC core now takes care of setting the bias level to
SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually
anymore either.
The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe()
can also be removed as the core will automatically do this after the CODEC
has been probed.

When being powered on, either initially on probe or when resuming from
suspend, the wm8971 configures the device for quick output capacitor
charging. Since the charging can take a rather long time (up to multiple
seconds) it is done asynchronously without blocking. A delayed work item is
run once the charging is finished and the device is switched to the target
bias level.
This all done asynchronously to the regular DAPM sequence accessing the same
data structures and registers without any looking, which can lead to race
conditions. Furthermore this potentially delays the start of stream on the
CODEC while the rest of the system is already up and running, meaning the
first bytes of audio are lost. It also does no comply with the assumption of
the DAPM core that if set_bias_level() returned successfully the device will
be at the requested bias level.
This patch slightly refactors things and makes sure that the caps charging
is properly integrated into the DAPM sequence. When transitioning from
SND_SOC_BIAS_OFF to SND_SOC_BIAS_STANDBY the part will be put into fast
charging mode and a work item will be scheduled that puts it back into
standby charging once the charging period has elapsed. If a playback or
capture stream is started while charging is in progress the driver will now
wait in SND_SOC_BIAS_PREPARE until the charging is done. This makes sure
that charging is done asynchronously in the background when the chip is
idle, but at the same time makes sure that playback/capture is not started
before the charging is done.

The delayed work used by the wm8971 driver to manage the caps charging
doesn't have any special requirements that would justify using a custom
workqueue, just use the generic system_power_efficient_wq instead.

If the registration of a debugfs directory fails this is treated as a
non-fatal error in ASoC and operation continues as normal. This means we
need to be careful and check if the parent debugfs directory exists if we
try to register a debugfs file or sub-directory. Otherwise we might end up
passing NULL for the parent and the file or directory will be registered in
the top-level debugfs directory.

Create the card debugfs directory at the begining of the initilization
rather then the end as various steps in the initilization sequence will try
to register files and sub-directories in the card directory.

Current soc_init_card_debugfs() is called from snd_soc_register_card()
but, soc_cleanup_card_debugfs() is called from soc_cleanup_card_resources(),
not from paired function.
This differences don't matter for now. But if anyone wants to implement
a proper hotplug/unplug, this difference would become clearer.
Now, we can assume that snd_soc_instantiate_card() and
soc_cleanup_card_resources() are paired function.
soc_init_card_debugfs() / soc_cleanup_card_debugfs() paired function
should be called from these.

All of the things in the CODEC probe, such as getting the regulators and
verifying the chip ID, are better done in bus probe. It is better to
fail during bus probe if this is the wrong chip and all resource
allocation should be done in the bus probe anyway. This patch merges
the CODEC probe into bus probe.

When codec is in slave mode, ASRC can suppress noise for asynchronous
MCLK and LRCLK or special I2S format. This patch defines an API to select
the clock source for specified filters. And the codec driver will turn on ASRC
for these filters if ASRC is selected as their clock source.

System clock is necessary for rt5670 JD function. We assume system
clock source will be set in machine driver. So there are two things
left we should do in codec driver.
1. Set sysclk to codec internal clock in probe since machine driver
may not do that before JD function is registered.
2. Power up PLL once sysclk source is switched to PLL.

Currently, we will configure dmic related pin definition if pdata.dmic_en
is true. However, there is no disable option in the enum. So, any dmic is
used, all 3 dmic related pins will be configured. It may cause unexpected
pin definition. This patch adds a disable item for each dmic enum and
take it as default. So the driver will not set the pin configuration if
we don't set dmicx_data_pin in platform data.
