iommu/amd: Add support for AVIC when SNP is enabled
With introduction of SNP, AVIC feature is now restricted by default.
In order to support AVIC on SNP-enabled system, The IOMMU driver needs to
check EFR2[SNPAVICSup] and enables the support by setting SNPAVICEn bit
in the IOMMU control register (MMIO offset 18h).
