We are seeing root ports on some desktop boards support D3cold for discrete graphics card. So when efifb is in use while graphics device isn't bound to a driver, PCI and ACPI will put the graphics to D3cold when runtime suspend kicks in, makes efifb stop working. So ensure the graphics device won't be runtime suspended, to keep efifb work all the time.
