[fireball] 19349: According to MSDN: "PnP Manager queries a device's BusRelations (child devices) when the device is enumerated".

According to MSDN: "PnP Manager queries a device's BusRelations (child
devices) when the device is enumerated".
This change implements this behaviour in reactos (thanks Filip Navara
for providing this good idea). Before, querying BusRelations was done
only for ACPI/BUS_EXTENDER DeviceType.
