ASoC: SOF: Introduce IPC3 ops
Add the IPC ops including the topology-related IPC ops for the current
version (IPC3, named after the current SOF firmware ABI major version 3.0)
of IPC supported by the SOF firmware and set it as default. The topology
IPC ops and the widget ops within the topology IPC ops are both
mandatory.

With the introduction of IPC3 ops, we define the list of tokens pertaining
to the AIF_IN/AIF_OUT widgets. Then these tokens are parsed during
topology parsing and saved as part of the swidget tuples array. Once
topology parsing is complete, these tokens will be applied to create the
IPC structure for the host component based on the topology widget_setup
op in ipc3_tplg_ops.

ASoC: SOF: IPC: Introduce IPC ops
In preparation for supporting a new IPC version that will be introduced
in the SOF firmware, add a new set of ops that will be version specific.

For now, the IPC ops contain only the topology-related ops for setting
up widgets and pipeline connections. It will be expanded later to also
abstract the IPC-specific items in the component driver and DAI driver.

ASoC: SOF: Convert the generic probe support to SOF client
Add a new client driver for probes support and move
all the probes-related code from the core to the
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.

ASoC: SOF: Introduce IPC SOF client support
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.

ASoC: SOF: dsp_arch_ops: add kernel log level parameter for oops and stack
To allow custom log level to be used for the DSP oops and stack print, add
a kernel log level parameter to the two ops.

Modify the xtensa oops and stack functions tom use this new log level
parameter.

Pass KER_ERR from snd_sof_get_status() to make sure that there is no
functional change with this new parameter.

ASoC: SOF: add support for dynamic pipelines with multi-core
This patch adds support for dynamic pipelines with multi-core
by using the platform-specific core_get/put() ops to
power up/down a core when a widget is set up/freed.

Along with this, a few redundant functions are removed:
1. sof_pipeline_core_enable() is no longer needed as the
pipeline core will be set up when the pipeline widget
is set up
2. sof_core_enable() is replaced with snd_sof_core_get()
4. core_power_up/down() DSP ops are deprecated and replaced with
core get/put ops.
5. Core power down in sof_widget_unload() during topology
removal is also removed as it is not really needed. For dynamic
pipelines, the cores will be powered off when they are not used.
For static pipelines, the cores will be powered off in the device
remove callback.

ASoC: SOF: prepare code to allocate IPC messages in fw_ready
The fixed maximum size of IPC message does not allow for large
transfers, e.g. for filter data. Currently such messages will
be divided into smaller pieces and sent to firmware in multiple
chunks. For future IPC, this strategy is not suitable.

The maximum IPC message size is limited by host box size which
can be known when firmware is ready, so the fw_ready callback
can allocate IPC messages with platform-specific sizes instead
of the current fixed-size.

To be compatible with released firmware, current platforms will
still use SOF_IPC_MSG_MAX_SIZE. For future platforms, there will
be a new fw_ready function and the platform-specific allocation
will take place there.

ASoC: SOF: Make Intel IPC stream ops generic
This operations should be generic as there is nothing Intel
specific. This works well for NXP i.MX8 stream IPC ops.

We start by moving sof/intel/intel-ipc.c into sof/stream-ipc.c and
rename the functions to be generic.

Notice that we use newly introduced snd_sof_dsp_mailbox_read
instead of sof_mailbox_read, to make sure that we are not
bound to existing MMIO memory access, and we allow platform
to implement their own memory access routines.

ASoC: SOF: core: debug: force all processing on primary core
The topology file currently provides information on which
pipeline/processing is to be scheduled on which DSP core.

To help diagnose potential issues, this patch provides an override of
the 'core' tokens to use the primary core (typically core0). Of course
this may result in a Core0 activity that exceeds hardware
capabilities, so this should only be used when the total processing
fits on DSP - possibly using firmware mockup processing and stubs.

No new dmesg log was added to avoid adding noise during topology
parsing, but the existing logs will show the primary core being used.

This is strictly for validation/debug, products should NEVER use this
override, the topology is assumed to be the description of the
firmware graph.
