Speed up uhub attachment considerably. Rather than powering up each port
individually then waiting for it to become stable, power them up all
at once and then delay. Don't even bother delaying if we are a root hub,
as this is handled separately in the event thread.
My laptop boot time is cut down from 30 sec to 25 sec with this change.
