Implement config_detach(), mostly from Chris Demetriou, modified slightly
by Ken Hornstein and myself.
Add flags to struct device, and define one as "active". Devices are
initially active from config_attach(). Their active state may be changed
via config_activate() and config_deactivate().
These new functions assume that the device being manipulated will recursively
perform the action on its children.
Together, config_deactivate() and config_detach() may be used to implement
interrupt-driven device detachment. config_deactivate() will take care of
things that need to be performed at interrupt time, and config_detach()
(which must run in a valid thread context) finishes the job, which may
