I don't understand why we pass this in as a function when as far as I
can see it should always be the standard operation provided by the core
- why not just always call the function?  We can tell at runtime if the
system is using DT so there's no issue there and there shouldn't be any
concerns with ACPI or other firmware interfaces.
