The MIPI DisCo specification for SoundWire defines the "mipi-sdw-link-N-subproperties", not the master-N properties. Fix to parse firmware information.
Please ignore this patch for now, there is a confusion in the spec itself that needs to be addressed by MIPI... Either there will be an errata issued, or we'll have to try both master- and link-N-properties to reconcile spec and actual implementations.
