ASoC: SOF: core: debug: force all processing on primary core
The topology file currently provides information on which
pipeline/processing is to be scheduled on which DSP core.
To help diagnose potential issues, this patch provides an override of
the 'core' tokens to use the primary core (typically core0). Of course
this may result in a Core0 activity that exceeds hardware
capabilities, so this should only be used when the total processing
fits on DSP - possibly using firmware mockup processing and stubs.
No new dmesg log was added to avoid adding noise during topology
parsing, but the existing logs will show the primary core being used.
This is strictly for validation/debug, products should NEVER use this
override, the topology is assumed to be the description of the
firmware graph.
