imp 8b10395635 Expose pci_add_resources to the outside world, add a 'force' flag to
force allocation of unallocated BARs (cardbus uses this to preallocate
everything).  Add a prefetchmask to allow for busses that get prefetch
hints to set them.  Addjust pci_add_map and pci_ata_maps to take a new
force flag which pci_add_resources will pass in.  Implement 'force' in
pci_add_map.  Write new value of allocated resource into the bar, if
the allocation succeeded (we should have done this before, but with
the new force the bug was very obvious).
