Public bug reported:

[Impact]
NVIDIA GPU becomes unusable after S3.

[Test]
The NVIDIA GPU works well after applying this patch.

[Fix]
Rewrite 0 to Intel PCI bridge 'Prefetchable Base Upper 32 Bits'.
This should be done by BIOS S3 code [1], but now the issue reappears, let's
do the same via Linux PCI subsystem.

[Regression Potential]
Low.
After applying this patch I haven't noticed any change on already
working PCI devices.
Also this patch is acked by PCI and ACPI maintainers, so we can be more
confident.
