iommu/vt-d: Add helper to flush caches for context change
This helper is used to flush the related caches following a change in a
context table entry that was previously present. The VT-d specification
provides guidance for such invalidations in section 6.5.3.3.
This helper replaces the existing open code in the code paths where a
present context entry is being torn down.
