Some parts of rt5682s CCF function are implemented by
'MICBIAS' and 'Vref2' dapm widgets.
There is a risk of causing not expected behavior if we
mix using dapm and CCF operations in machine specific code.
This patch reduces the coupling.

Control the regulators separately instead of using regulator_bulk to
accord to the timing request in the datasheet.

Some powers were changed during the jack insert detection and clk's
enable/disable in CCF.
If in parallel, the influence has a chance to detect the wrong jack
type.
We refer to the below commit of the variant codec (rt5682) to fix
this issue.
ASoC: rt5682: Fix deadlock on resume
1. Remove rt5682s_headset_detect in rt5682s_jd_check_handler and
use jack_detect_work instead of.
2. Use dapm mutex used in CCF to protect most of jack_detect_work.

When the system plays a sound immediately after resuming from S3,
it could hear a little pop from headphones.
It is due to the HP was unmuted before the completion of
jack re-detection finished in parallel.
This patch adds a lock to make sure the HP unmute after jack detect handler,
and adds a few depop changes.

When codec's ASRC was enabled, the DA and AD filters use
the reference clk which tracks the I2S clks.
And if the I2S clks' timing of open and close are not expected,
this patch allows the filters to switch to use sysclk if
ASRC's ref clks disappeared and could fix the below possible issues:
1. Avoid DA filter to keep surplus samples.
2. Avoid that AD filter works failed during dapm's power on.
For example,
if I2S clks were closed before dacdat during playback off
due to jack unplug, it causes ref clks disappeared and
DA filter remained some samples which will produce pop noise
on the next HP playback.
ASRC auto-disable could clear the samples during the playback off.
