What I think could be also done is to collect the handles with these nodes
to a list (requires struct list_head in struct acpi_device) in order to
create the devices after tree traversal.

This approach might be usable for even getting rid of the second pass
altogether, with the tradeoff of requiring a little bit of extra memory.
