Add missing compatible/model to Yellow+CM5 DTS (#4057)

The refactored DTS from #4036 was missing compatible and model strings for CM5
on Yellow. While this shouldn't cause any issues, add them back.

+Although it's not used anywhere currently, compatible string and model name
+were lost when DTS was simplified after 6.12.y update. Add it back to override
+the CM5 default.
