iommu/vt-d: Cleanup use of iommu_flush_iotlb_psi()
Use cache_tag_flush_range() in switch_to_super_page() to invalidate the
necessary caches when switching mappings from normal to super pages. The
iommu_flush_iotlb_psi() call in intel_iommu_memory_notifier() is
unnecessary since there should be no cache invalidation for the identity
domain.
Clean up iommu_flush_iotlb_psi() after the last call site is removed.
