Merge series "ASoC: SOF: component UUID support for 5.10" from Kai Vehmanen...

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.

Keyon Jie (16):
  ASoC: SOF: tokens: add token for component UUID
  ASoC: SOF: add comp_ext to struct snd_sof_widget
  ASoC: SOF: topology: create component extended tokens
  ASoC: SOF: topology: parse comp_ext_tokens for all widgets
  ASoC: SOF: use the sof_ipc_comp reserved bytes for extended data
  ASoC: SOF: topology: add helper for setting up IPC component
  ASoC: SOF: append extended data to sof_ipc_comp_dai
  ASoC: SOF: append extended data to sof_ipc_comp_mixer
  ASoC: SOF: append extended data to sof_ipc_comp_volume
  ASoC: SOF: append extended data to sof_ipc_comp_host
  ASoC: SOF: append extended data to sof_ipc_comp_src
  ASoC: SOF: append extended data to sof_ipc_comp_asrc
  ASoC: SOF: append extended data to sof_ipc_comp_tone
  ASoC: SOF: append extended data to sof_ipc_comp_process
  ASoC: SOF: append extended data to sof_ipc_comp_mux
  ASoC: SOF: topology: make process type optional
