platform/x86/amd: pmc: Add Lenovo Legion Go 2 to pmc quirk list 

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.

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4618
