Lu Baolu 89395ccedb iommu: Add device-centric DMA ownership interfaces 
These complement the group interfaces used by VFIO and are for use by
iommufd. The main difference is that multiple devices in the same group
can all share the ownership by passing the same ownership pointer.

Move the common code into shared functions.
