Bug description:
  [Impact]
  EFIFB stops working after graphics device is runtime suspended in
  D3cold.

  [Fix]
  Prevent the graphics device from being runtime suspended.

  [Test]
  With the patch applied, using efifb on graphics device without driver
  always work, because the device stays at D0 all the time.

  [Where problems could occur]
  Potentially this can affect power consumption, if user expects to put
  graphics device to D3cold, and is fine to get a broken efifb.
