- Add explanatory comments across intel driver to clarify metadata parsing.
- Ensure driver selection preserves runtime options (e.g. "intel/ddc_override:AABB")
so driver-specific metadata is passed through to the host and available to
drivers via host.hci_metadata.
- Ensure transport parsing regex and metadata extraction so transport/source
metadata is populated and visible to drivers.
- Example usage: passing [driver=intel/ddc_override:AABB] will be preserved and
can be consumed by the Intel driver to apply a DDC override blob.
