iommu/vt-d: Remove incorrect PSI capability check
The PSI (Page Selective Invalidation) bit in the capability register
is only valid for second-level translation. Intel IOMMU supporting
scalable mode must support page/address selective IOTLB invalidation
for first-level translation. Remove the PSI capability check in SVA
cache invalidation code.
