> table with the properties of 'aliases' node and function
> of_alias_get_id for drivers to find alias id from the lookup table.
> 
> v3: Split out automatic addition of aliases on id lookup so that it can be
>     debated separately from the core functionality.
> v2: - Add of_chosen/of_aliases populating and of_alias_scan() invocation
>     for OF_PROMTREE.
>     - Add locking
>     - rework parse loop
