John Baldwin 98bbce55fa Adjust the code to probe for the PCI config mechanism to use.
- On amd64, just assume type #1 is always used.  PCI 2.0 mandated
  deprecated type #2 and required type #1 for all future bridges which
  was well before amd64 existed.
- For i386, ignore whatever value was in 0xcf8 before testing for type #1
  and instead rely on the other tests to determine if type #1 works.  Some
  newer machines leave garbage in 0xcf8 during boot and as a result the
  kernel doesn't find PCI at all (which greatly confuses ACPI which expects
  PCI to exist when PCI busses are in the namespace).
