iommu/vt-d: Decouple PASID & PRI enabling from SVA
Previously the PCI PASID and PRI capabilities are enabled in the path of iommu device probe only if INTEL_IOMMU_SVM is configured and the device supports ATS. As we've already decoupled the I/O page fault handler from SVA, we could also decouple PASID and PRI enabling from it to make room for growth of new features like kernel DMA with PASID, SIOV and nested translation. At the same time, the iommu_enable_dev_iotlb() helper is also called in iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) path. It's unnecessary and duplicate. This cleanups this helper to make the code neat.
