  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
