Lu Baolu e5e04d0519 iommu/vt-d: Check whether device requires bounce buffer 
This adds a helper to check whether a device needs to
use bounce buffer. It also provides a boot time option
to disable the bounce buffer. Users can use this to
prevent the iommu driver from using the bounce buffer
for performance gain.
