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.
