  [Feature] USB2.0 Port power off mechanism

Bug description:
  This is an Intel-specific feature.  When a USB port is powered off, VBUS is
  removed, and port events are lost (device connect & disconnect, remote wake
  from USB device suspend, and overcurrent events).  OEMs may power-gang several
  ports together, so VBUS may not be removed until several ports are powered off.
