Add SOF_TKN_COMP_SCHED_DOMAIN and connect it to struct snd_sof_widget
comp_domain member, with new get_token_comp_domain() function.
The logic is such that if the topology attribute is not present in the
widget node the corresponding IPC4 extension value is taken from the
module's manifest like before. But if the attribute is found and
recognized its value overrides what is there in the manifest.

New tokens are added to topology:
1202: SOF_TKN_STREAM_PLAYBACK_PAUSE_SUPPORTED
1203: SOF_TKN_STREAM_CAPTURE_PAUSE_SUPPORTED
The new tokens are used to advertise support for PAUSE/RESUME operation on
a PCM device depending on firmware product, use case, pipeline topology.
The snd_sof_pcm_stream.pause_supported is updated to reflect the advertised
value for the PCM device.
If the token does not exist then the pause_supported is set to false.
Note: it is up to the platform code to use this flag to decide to advertise
the PAUSE support for user space or not.

Add logic for setting up and tearing down chained DMA connections.
Since pipelines are not used, all the logic to set the pipeline states
can be bypassed, with only the DMA programming sequences remaining. In
addition the same format needs to be used for host- and link-DMA,
without the usual fixup to use the S32_LE format on the link.
Note however that for convenience and compatibility with existing
definitions, the topology relies on the concept of pipelines with a
'USE_CHAIN_DMA' token indicating that all the logic shall be bypassed.
Unlike 'normal' ALSA sequences, the chain DMA is not programmed in
hw_params/hw_free. The IPC message to set-up and tear-down chained DMA
are sent in sof_ipc4_trigger_pipelines(), but the contents prepared
earlier.
Chained DMA is only supported by the Intel HDA DAI for now, and only
S16_LE and S32_LE formats are supported for now.

Introduce a new struct sof_ipc4_pin_format which contains the pin index
and the buffer size. Replace the type of available input/output audio
formats in struct sof_ipc4_available_audio_format with this new struct
type and rename them to input_pin_fmts and output_pin_fmts.
Also, add a new token, SOF_TKN_CAVS_AUDIO_FORMAT_PIN_INDEX that will be
used to parse the pin index for the audio format from topology.
Currently we only set the audio format for Pin 0 in topology, so the
default value will be 0 for all audio formats.
Finally, parse the pin_index and the input/output buffer sizes
along with audio formats into the pin_format arrays in struct
sof_ipc4_available_audio_format. This makes the base_config array in struct
sof_ipc4_available_audio_format redundant. So remove it. This change
will allow the addition of audio formats for the non-zero pins in
topology transparent to the topology parser in the kernel.

Add support for parsing sink/source pin binding array
per widget from topology. The pin binding arrays will
be used to determine the source and sink queue IDs during
widget binding for widget that requires special pin binding.
An example of widget that requires special pin binding is
the smart amplifier widget, its feedback sink pin has to be
connected to a capture DAI copier for codec feedback, while
the other sink pin has to be connected to a host DAI copier.
Pin ID is required during widget binding for correct route setup.
Conversely, the pin ID for 'generic' pins is not defined in the
topology and will be allocated by the kernel dynamically. When
only one pin is supported, the pin ID shall always be zero. When
more than one pin is supported, the pin ID is determined with the
ID allocation mechanism in the kernel.

Today, we set up all widgets required for all PCM streams
at the time of topology parsing even if they are not
used. An optimization would be to only set up the widgets
required for currently active PCM streams. This would give
the FW the opportunity to power gate unused memory blocks,
thereby saving power.
For dynamic pipelines, the widgets in the connected DAPM path
for each PCM will need to be set up at runtime. This patch
introduces a new token, DYNAMIC_PIPELINE, for scheduler type
widgets that indicate whether a pipeline should be set up
statically during topology load or at runtime when the PCM is
opened. Introduce a new field called dynamic_pipeline_widget
in struct snd_sof_widget to save the value of the parsed token.
The token is set only for the pipeline (scheduler type)
widget and must be propagated to all widgets in the same
pipeline during topology load. Introduce another field called
pipe_widget in struct snd_sof_widget that saves the pointer to
the scheduler widget with the same pipeline ID as that of the
widget. This field is populated when the pipeline completion
callback is invoked during topology loading.
