[SRU] [F/G/Unstable/OEM-5.10] [PATCH 0/1] Fix broken efifb on graphics device without driver

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1914411

[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.
