platform/x86/amd: pmc: Apply nvme quirk to HP 15s-eq2xxx
HP 15s-eq2xxx is an older Lucienne laptop that has a problem resuming
from s2idle when IOMMU is enabled. The symptoms very closely resemble
that of the Lenovo issues with NVME resume. Lucienne was released in
a similar timeframe as the Renoir / Cezanne Lenovo laptops and they
may have similar BIOS code.
Applying the same quirk to this system allows the system to work with
IOMMU enabled and s2idle resume to work.
