Keshavamurthy, Anil S 994a65e25d Intel IOMMU: PCI generic helper function 
When devices are under a p2p bridge, upstream transactions get replaced by the
device id of the bridge as it owns the PCIE transaction.  Hence its necessary
to setup translations on behalf of the bridge as well.  Due to this limitation
all devices under a p2p share the same domain in a DMAR.

We just cache the type of device, if its a native PCIe device
or not for later use.
