The QC ADSP is able to support USB playback endpoints, so that the main
application processor can be placed into lower CPU power modes. This adds
the required AFE port configurations and port start command to start an
audio session.
Specifically, the QC ADSP can support all potential endpoints that are
exposed by the audio data interface. This includes isochronous data
endpoints, in either synchronous mode or asynchronous mode. In the latter
case both implicit or explicit feedback endpoints are supported. The size
of audio samples sent per USB frame (microframe) will be adjusted based on
information received on the feedback endpoint.
Some pre-requisites are needed before issuing the AFE port start command,
such as setting the USB AFE dev_token. This carries information about the
available USB SND cards and PCM devices that have been discovered on the
USB bus. The dev_token field is used by the audio DSP to notify the USB
offload driver of which card and PCM index to enable playback on.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

Merge series from Rob Herring <robh@kernel.org>:
This is a series is part of ongoing clean-ups related to device
matching and DT related implicit includes. Essentially of_device.h has
a bunch of implicit includes and generally isn't needed any nore except
for of_match_device(). As we also generally want to get rid of
of_match_device() as well, I've done that so we're not updating the
includes twice.
Move the includes of binding headers from Qualcomm SoC sound drivers
headers to unit files actually using these bindings. This reduces the
amount of work for C preprocessor and makes usage of bindings easier to
follow. No impact expected on the final binaries.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

msm_routing_put_audio_mixer() can return incorrect value in various scenarios.
scenario 1:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 0
return value is 0 instead of 1 eventhough value was changed
scenario 2:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
return value is 1 instead of 0 eventhough the value was not changed
scenario 3:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 0
return value is 1 instead of 0 eventhough the value was not changed
Fix this by adding checks, so that change notifications are sent correctly.

Stream IDs are reused across multiple BackEnd mixers, do not reset the
stream mixers if they are not already set for that particular FrontEnd.
Ex:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
would set the MultiMedia1 steam for SLIMBUS_0_RX, however doing below
command will reset previously setup MultiMedia1 stream, because both of them
are using MultiMedia1 PCM stream.
amixer cset iface=MIXER,name='SLIMBUS_2_RX Audio Mixer MultiMedia1' 0
reset the FrontEnd Mixers conditionally to fix this issue.
This is more noticeable in desktop setup, where in alsactl tries to restore
the alsa state and overwriting the previous mixer settings.

At the moment it is necessary to set up the DAPM routes between
front-end AIF<->DAI explicitly in the device tree, e.g. using
audio-routing =
"MM_DL1", "MultiMedia1 Playback",
"MM_DL3", "MultiMedia3 Playback",
"MM_DL4", "MultiMedia4 Playback",
"MultiMedia2 Capture", "MM_UL2";
This is prone to mistakes and (sadly) there is no clear error if one
of these routes is missing. :(
Actually, this should not be necessary because the ASoC core normally
automatically links AIF<->DAI within snd_soc_dapm_link_dai_widgets().
This is done using the "stname" parameter of SND_SOC_DAPM_AIF_IN/OUT.
For SND_SOC_DAPM_AIF_IN("MM_DL1", "MultiMedia1 Playback", 0, 0, 0, 0),
it should create the route from above: MM_DL1 <-> MultiMedia1 Playback.
This does not work at the moment because the AIF widget (MM_DL1)
and the DAI widget (MultiMedia1 Playback) belong to different
DAPM contexts (q6routing / q6asm-dai).
Fix this by declaring the AIF widgets in the same driver as the DAIs
(q6asm-dai). Now the routes above are created automatically
and no longer need to be specified in the device tree.
This is also more consistent with the back-end AIFs which are already
declared in q6afe-dais instead of q6routing. q6routing should only link
the components together using mixers.

Most of the DAPM widgets for DSP ASoC components reuse reg field
of the widgets for its internal calculations, however these are not
real registers. So read/writes to these numbers are not really
valid. However ASoC core will read these registers to get default
state during startup.
With recent changes to ASoC core, every register read/write
failures are reported very verbosely. Prior to this fails to reads
are totally ignored, so we never saw any error messages.
To fix this add dummy read/write function to return default value.
