ASoC: SOF: Intel: CNL: register probes client

Register the client device for probes support on the
CNL platform. Creating this client device alleviates the
need for modifying the sound card definitions in the existing
machine drivers to add support for the new probes feature in
the FW. This will result in the creation of a separate sound
card that can be used for audio data extraction from user
specified points in the audio pipeline.
