[PATCH] ia64: Fix PCI root bridge resources to handle prior allocations.

(alloc_resources):  Use insert_resource(), not request_resource(), to
allocate PCI root bridge windows.  This fixes the problem
where root bridge window allocation fails because an early
driver (like VGA) has already allocated things.
