Add a new client driver for probes support and move all the probes-related code from the core to the client driver. The probes client driver registers a component driver with one CPU DAI driver for extraction and creates a new sound card with one DUMMY DAI link with a dummy codec that will be used for extracting audio data from specific points in the audio pipeline. The probes debugfs ops are based on the initial implementation by Cezary Rojewski and have been moved out of the SOF core into the client driver making it easier to maintain. This change will make it easier for the probes functionality to be added for all platforms without having the need to modify the existing(15+) machine drivers.

This option enables strict ABI checks for firmware and topology

This option will stop topology creation and firmware load upfront.
