David Lazar 3bde7ec13c platform/x86: Add s2idle quirk for more Lenovo laptops 
When suspending to idle and resuming on some Lenovo laptops using the
Mendocino APU, multiple NVME IOMMU page faults occur, showing up in
dmesg as repeated errors:

nvme 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000b
address=0xb6674000 flags=0x0000]

The system is unstable afterwards.

Applying the s2idle quirk introduced by commit 455cd867b8 ("platform/x86:
thinkpad_acpi: Add a s2idle resume quirk for a number of laptops")
allows these systems to work with the IOMMU enabled and s2idle
resume to work.
