iommu/vt-d: Factor out invalidation descriptor composition

Browse source

Separate the logic for constructing IOTLB and device TLB invalidation
descriptors from the qi_flush interfaces. New helpers, qi_desc(), are
introduced to encapsulate this common functionality.

Moving descriptor composition code to new helpers enables its reuse in
the upcoming qi_batch interfaces.

No functional changes are intended.
