Add support for header type == 1 devices (PCI 2.1 compatible PCI to PCI
bridges with support for 64 bit memory addresses and 32 bit I/O addresses).
The code is not complete. It ignores the upper half of the long addresses.
This is not a problem on PC compatible systems, but has to be fixed for
real computers.
