Add support for using the rt5682s codec together with rt1015p on
mt8192-mt6359 machines. All configurations are shared with the rt5682
codec variant, so simply select the SND_SOC_RT5682S config to ensure the
codec is present and set the correct card name. The codec will be linked
to by pointing to it in the headset-codec property in the devicetree.
While at it, also create macros for the names of the different codec
variants supported by this driver, as well as rename occurrences of
rt1015p_rt5682 to rt1015p_rt5682x, since they are shared between rt5682
and rt5682s.

Huawei Matebook D15 uses two different GPIOs are used to control the output:
- gpio0 controls the speaker output;
- gpio1 controls the headphone output.
Changing both at the same time cause spurious events that are mis-interpreted
as input events, causing troubles on apps. So, a delay is needed before turning
on such gpios.
Also, the headset microphone is connected to MIC1, instead of MIC2 port.
With this patch, plugging a headphone causes a jack event to trigger the speaker
supply, powering down the speaker and powering up the headphone output.
Removing the headphone also triggers the power supply, powering up the speaker
and powering down the headphone.
The headset microphone also works.
Based on experimental tests, Huawei Matebook D15 actually uses
both gpio0 and gpio1: the first one controls the speaker, while
the other one controls the headphone.
Also, the headset is mapped as MIC1, instead of MIC2.
So, add a quirk for it.

SIDO(Single-Inductor Dual-Ouput) Buck powers up both analog and digital
circuits along with internal memory, powering off this is the last thing
that codec should do when going to very low power.
Current code was powering off this Buck if there are no users of sysclk,
which is not correct. Powering off this buck will result in no register access.
This code path was never tested until recently after adding pm support
in SoundWire controller. Fix this by removing the buck poweroff when the
codec is active and also the code that is not used.
Without this patch all the read/write transactions will never complete and
results in SLIMBus Errors like:

This patch takes a defensive programming and paranoid approach in case
the parent device (SoundWire) is pm_runtime resumed but the rt711
device is not. In that case, during the attachment and initialization,
a jack detection workqueue can be scheduled. Since the pm_runtime
suspend routines will not be invoked, the sequence to cancel all
deferred work is not executed, and the jack detection could happen
after the bus stops operating, leading to a timeout.
This patch applies the same solution to rt5682, based on the
similarities between codec drivers. The race condition with rt5682 was
not detected experimentally though.

error in soc_init_component_debugfs(). The proposed solution allows
other drivers to adopt the same approach with minimal effort.
With the patch the error is gone and that's the debugfs entries.
/sys/kernel/debug/asoc/P230-Q200/acodec:c1105400.audio-controller
/sys/kernel/debug/asoc/P230-Q200/hdmi:c1105400.audio-controller
/sys/kernel/debug/asoc/P230-Q200/cpu:c1105400.audio-controller
On a S905W-based system I get the following error:
debugfs: Directory 'c1105400.audio-controller' with parent 'P230-Q200' already present!
Turned out that multiple components having the same name triggers this
error in soc_init_component_debugfs(). With the patch the error is gone
and that's the debugfs entries.

Allow the component debugfs_prefix to be set from
snd_soc_component_driver. First use case is avoiding a duplicate
debugfs entry error in case a device has multiple components
which have the same name therefore.
Note that we don't set component->debugfs_prefix if it's set already.
That's needed because partially component->debugfs_prefix is set
before calling snd_soc_component_initialize().
