The MIPI DisCo specification for SoundWire defines the "mipi-sdw-link-N-subproperties" for slaves and "mipi-sdw-master-N-subproperties" for controllers. This is a mistake that was not identified until now.
Existing Intel DSDT tables use 'link' everywhere, and the MIPI spec will be updated to deprecate "mipi-sdw-master-N-subproperties"
Fix to parse firmware information on existing devices. If we ever see a system with 'master-N-subproperties' I guess we'll have to try both.
