Fix a busted constant related to PCI configuration acess method #1.  The
reserved bits in the port that must be zero are 24:30, not 20:30.  Bits
16:23 are used to set the bus number.  This meant that when we tested for
config mechanism #1, if the previous PCI configuration transaction sent
used a bus number greater than 15, one of the bits in 20:23 would be
non-zero and we would fail to use config mechanism #1 and thus fail to see
that PCI existed on the machine at all.
