On a platform shutdown, the expectation for most drivers is that
userspace tasks will release all resources. When those sequences do
not complete, it can be the case that PCM devices exposed by ALSA
cards are used *after* the DSP shutdown completes, leading to a
platform hang.

When the clients and machine drivers provide an _unregister callback,
let's invoke it in the shutdown sequence.

In the case like dmaengine which's not a dai but as a component, the
num_dai is zero, dmaengine component has the same component_of_node
as cpu dai, when cpu dai component is not ready, but dmaengine component
is ready, try to get cpu dai name, the snd_soc_get_dai_name() return
-EINVAL, not -EPROBE_DEFER, that cause below error:

asoc-simple-card <card name>: parse error -22
asoc-simple-card: probe of <card name> failed with error -22

The sound card failed to probe.

So this patch fixes the issue above by skipping the zero num_dai
component in searching dai name.

On BIAS STANDBY->OFF transition the current implementation sleeps
600ms on suspend in order to discharge the chip. The suspend is
propagated from "snd_soc_suspend" call for all audio cards in a
serial fashion, thus in case of boards like i.MX8DXL EVK which has
3 distinct WM8960 codecs the total cumulated sleep on suspend is 1.8
seconds.

On the other hand the BIAS OFF->STANDBY transition happens
asynchronously with regard to "snd_soc_resume" - the call is
propagated from "soc_resume_deferred" which is just scheduled
from "snd_soc_resume", each card having its own work scheduled to
execute "soc_resume_deferred" call.

The patch performs discharge completion on BIAS OFF->STANDBY transition
so that the cumulated effect on suspend described above is avoided
and discharge is completed in paralel in case of multiple WM8960
codecs on the board.

When checking if the requested parameters are supported, the driver uses
PCM3168A_FMT_DSP_MASK to check for PCM3168A_FMT_DSP_* values.

However, formally not only PCM3168A_FMT_DSP_* values match that
condition, PCM3168A_FMT_I2S_TDM and PCM3168A_FMT_LEFT_J_TDM also do.

The check still gives correct result because those extra values can't
be in 'fmt' at the check location. Still, to make the code less cryptic,
better to compare 'fmt' with PCM3168A_FMT_DSP_* values explicitly.

The TLV320ADC3001/3101 have an internal DSP, which can either be
used in various preset configurations (called "Processing Blocks"
in the data sheet), or as a freely programmable (using the
"PurePath Studio" graphical programming tool from TI) but rather
small DSP ("miniDSP").

Using the default configuration (PRB_R1) it's possible to set up
filtering using a first-order IIR, which can be useful for adding
a digital high pass filter to the signal chain, for instance.

This patch adds support for configuring the IIR filter coefficients.
The filter itself is always enabled; the default coefficients
implement a pass-through function.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

The Linux SOF implementation is historically monolithic in a sense that all
features accessible in the firmware can be used via the snd_sof_dev struct in
one way or another.

Support for features can not be added or removed runtime and with the current
way of things it is hard if not impossible to implement support for dynamic
feature support when based on the firmware manifest we can easily enable/access
independent modules with the SOF.

In order to be able to support such modularity this series introduces a small
framework within SOF for client support using the Auxiliary bus.

Client drivers can be removed runtime and later re-loaded if needed without
affecting the core's behaviour, but it is the core's and the platform's duty
to create the Auxiliary devices usable in the platform and via the firmware.

There is still a need for SOF manifest update to convey information about
features to really make the full dynamic client device creation.

The series will introduce the core SOF client support and converts the generic
ipc flood test, ipc message injector and the probes (Intel HDA only) to a client
driver.

The probes client driver registers a component driver
with one CPU DAI driver for extraction and creates a
new sound card with one DUMMY DAI link with a dummy codec
that will be used for extracting audio data from specific
points in the audio pipeline.

The probes debugfs ops are based on the initial
implementation by Cezary Rojewski and have been moved
out of the SOF core into the client driver making it
easier to maintain. This change will make it easier
for the probes functionality to be added for all platforms
without having the need to modify the existing(15+) machine
drivers.

A client in the SOF (Sound Open Firmware) context is a driver that needs
to communicate with the DSP via IPC messages. The SOF core is responsible
for serializing the IPC messages to the DSP from the different clients.

One example of an SOF client would be an IPC test client that floods the
DSP with test IPC messages to validate if the serialization works as
expected.

Multi-client support will also add the ability to split the existing audio
cards into multiple ones, so as to e.g. to deal with HDMI with a dedicated
client instead of adding HDMI to all cards.

This patch introduces descriptors for SOF client driver and SOF client
device along with APIs for registering and unregistering a SOF client
driver, sending IPCs from a client device and accessing the SOF core
debugfs root entry.

Along with this, add a couple of new members to struct snd_sof_dev that
will be used for maintaining the list of clients.
