Mostly extracted from nested SVA/SVM series based on review comments of v7.

This series also adds a few important fixes for native use of SVA. Nested
SVA new code will be submitted separately as a smaller set. Based on the
core branch of IOMMU tree staged for v5.5, where common APIs for vSVA were
applied.
