  1. ASoC: SOF: Add support for pause supported tokens from topology 

    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.

  2. ASoC: SOF: Intel: hda-pcm: Follow the pause_supported flag to drop PA… 

    …USE support

If the stream's pause_supported flag is false then mask out the PAUSE
support, so user space will be prevented to use it.

Introduce a module parameter to ignore the pause_supported flag, named as
force_pause_support to allow testing of the PAUSE feature.
