Lu Baolu c4d27ffaa8 iommu/vt-d: Add cache tag invalidation helpers
Add several helpers to invalidate the caches after mappings in the
affected domain are changed.

- cache_tag_flush_range() invalidates a range of caches after mappings
  within this range are changed. It uses the page-selective cache
  invalidation methods.

- cache_tag_flush_all() invalidates all caches tagged by a domain ID.
  It uses the domain-selective cache invalidation methods.

- cache_tag_flush_range_np() invalidates a range of caches when new
  mappings are created in the domain and the corresponding page table
  entries change from non-present to present.
