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.
