ia64: Fix resource assignment for root busses

Browse source 
ia64 was assigning resources to root busses after allocations had
been made for child busses.  Calling pcibios_setup_root_windows() from
pcibios_fixup_bus() solves this problem by assigning the resources to
the root bus before child busses are scanned.
