Adds a CONFIG_MAX_PCI_BUSES to pci_locate_device()
Default is 255. This allows mainboard configs for working across various groups of boards that differ a device that may not loaded. If you search for a device that is not loaded and max buses is 255 then there can be up to a 8 second delay to search the entire PCI space. Board configs that know thier max bus can limit this search space. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2273 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
