iommu/vt-d: Refactor IOTLB and Dev-IOTLB flush for batching

Browse source

Extracts IOTLB and Dev-IOTLB invalidation logic from cache tag flush
interfaces into dedicated helper functions. It prepares the codebase
for upcoming changes to support batched cache invalidations.

To enable direct use of qi_flush helpers in the new functions,
iommu->flush.flush_iotlb and quirk_extra_dev_tlb_flush() are opened up.

No functional changes are intended.
