This provides better semantics as a standalone DEVMETHOD for device_attach as bus drivers should remove child devices they created as part of detach cleanup. The implementation calls bus_detach_children() first to permit child devices an opportunity to veto the detach operation. If that succeeds, device_delete_children() is used to delete the child devices. This requires fixing various drivers that were deleting devices explicitly (via a device_t pointer cached in the softc) after calling bus_generic_detach to stop doing that and just rely on bus_generic_detach to remove child devices.
