Merge series "ASoC: SOF: component UUID support for 5.10" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:
This series adds support for UUID based component identification in SOF. UUIDs provide a more scalable alternative to the old component type based approach to identify which DSP components should be loaded. More detailed description of UUID usage in SOF is available in: https://thesofproject.github.io/latest/developer_guides/uuid/ UUID support is an incremental update to the SOF IPC interface. Driver remains compatible with pre-UUID (ABI <3.17) firmware versions.
