iommu/vt-d: Multiple descriptors per qi_submit_sync()
Current qi_submit_sync() only supports single invalidation descriptor
per submission and appends wait descriptor after each submission to
poll the hardware completion. This extends the qi_submit_sync() helper
to support multiple descriptors, and add an option so that the caller
could specify the Page-request Drain (PD) bit in the wait descriptor.
