I mean that each device providing resources of the new type would need
to register its resources to the same root resource with non-conclicting
addresses. Having resources hanging in the air without a parent pointer
is not good, although we seem to be doing that for a lot of platform
devices these days, where we just pass the struct resource from platform
code to a driver without ever registering it at each end.
