pci driver quirk to re-train link on resume
Just for completeness, attaching a hacky driver quirk patch to re-train the link on resume. On my otherwise unaffected notebook, this raises the link speed of the gpu from 0001 (2.5 GT/s) to 0003 (8GT/s) on resume.
Does not have any effect on the aforementioned Alienware, but at least it told that this device was already at the maximum reachable speed of 5GT/s.
