Christian Helmuth 2232b33b8e pci_decode: limit bus parsing to subordinate buses
While this approach still scans "holes" in the bus range, it stops
scanning at the maximum subordinate bus number reachable from the base
PCI bus at the host bridge. Startup under Qemu no longer takes about 12
seconds for scanning 256 buses.
