iommu/vt-d: Add qi_batch for dmar_domain
Introduces a qi_batch structure to hold batched cache invalidation
descriptors on a per-dmar_domain basis. A fixed-size descriptor
array is used for simplicity. The qi_batch is allocated when the
first cache tag is added to the domain and freed during
iommu_free_domain().
