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.
