A bus_space_reserve of some such is long overdue;  my point is, we don't
want to actually *map* it, merely mark it as used.

This is true for a lot of other things in ACPI land.  E.g., we should
reserve regions for all devices, whether or not a driver attaches.  But
then, what we need is probably a resource manager, because a driver
might attach later.
