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.
