/* Reconfigure all I/O base address registers for a range of PCI busses
 * (from and including 'bus_from' up to and not including 'bus_to').
 * adding an offset. This involves adjusting the base and limit registers
 * of PCI-PCI bridges, too.
 *
 * RESTRICTIONS: 'offset' must be 4k aligned (PCI req.); no argument check
 *          on the bus numbers is done.
 *
 * RETURNS: 0 on success and a number > 0 indicating the number of
 *          non-32bit bridges found where the offset couldn't be added.
 *          Devices behind such a bridge are not accessible through I/O
 *          and should probably be switched off (not done by this code).
