ASoC: Intel: catpt: Synchronize stream access

Streams may have individual controls assigned to them e.g.: volume
control in case of offload streams.

If such a stream is running and simultaneously its controls are being
manipulated, both processes are touching the exact same descriptors -
access to these must be synchronized. Replace spinlock with mutex as
IPCs are non-atomic operations and add proper locking for all
->stream_list users.
