Subject: [PATCH 0/2] iommu/amd: Misc Update for Virtual APIC support

First, this series simplifies existing feature detection and enablement of
GAM and GALog features, which are prerequisite for Virtual APIC (AVIC)
support. 

Second, it fixes the warning reported here https://lkml.org/lkml/2022/7/20/1135.

Last, it introduces new enablement for IOMMU to support AVIC on
SNP-enabled system.

Best Regards,
Suravee
