Konstantin Belousov 9d0bc6d88f Add support for the PCI(e)-PCI bridges to the Intel VT-d driver. The 
bridge takes ownership of the transaction, so bsf of the requester is
the bridge and not a device behind it.  As result, code needs to walk
the hierarchy up to use correct context.

Note that PCIe->PCI-X bridges are not handled quite correctly since
such bridges are allowed to only take ownership of some transactions.
Also, weird but unrealistic cases of PCIe behind PCI bus are also not
handled.

Still, the patch provides significant step forward for the bridge
handling.
