[ Upstream commit f945afe01c6768dcfed7868c671a26e1164c2284 ]

The Lenovo Legion Go 2 takes a long time to resume from suspend.
This is due to it having an nvme resume handler that interferes
with IOMMU mappings. It is a common issue with older Lenovo
laptops. Adding it to that quirk list fixes this issue.
