intel_iommu: Add support for translation for devices behind bridges
- Use a hash table indexed on bus pointers to store information about buses
instead of using the bus numbers.
Bus pointers are stored in a new VTDBus struct together with the vector
of device address space pointers indexed by devfn.
- The bus number is still used for lookup for selective SID based invalidate,
in which case the bus number is lazily resolved from the bus hash table and
cached in a separate index.
