Scan policies describe the way a bus should scan the system to search
for possible devices.
Three flags are introduced:
RTE_BUS_SCAN_UNDEFINED: Configuration is irrelevant for this bus
RTE_BUS_SCAN_WHITELIST: Scanning should be limited to declared devices
RTE_BUS_SCAN_BLACKLIST: Scanning should exclude only declared devices
