Changelog v1..v2:
- Correct DE2 bus enum to reflect fallback devices accurately.

Changelog v2..v3:
- Separate content into three patches for three separate subsystems

Changelog v5..v6:
- Increase reg maxItems to 3.

Changelog v9..v10:
- Remove maxItems, this was added in error to the bus binding (rather than the mixer binding) when it was split from the other bindings in an earlier revision.
