We can add a CONFIG_PCI_MAX_ROOT_BUS setting to SeaBIOS' config.h

If we don't want to compile in a max, and it's not reasonable to
autodetect it, then I guess we could have coreboot pass in the max to
SeaBIOS via the coreboot table.

Finally, I suppose SeaBIOS could just scan all 256 buses.  (Does
anyone know if a bus is guaranteed to have a device 0?  If so, that
would speed the scan significantly.)
