LEON PCI: host bridge driver support for probing dev0=AD16
Before the LIBPCI didn't probe device0 (AD16), the host bridge
drivers used bus=dev=func=0 to internally probe the host bridge's
target interface. Now that LIBPCI uses bus=dev=func=0 to access
device0, bus=0xff is introduced internally to identify the
host bridge target configuration space.
