Subject: [PATCH 0/2] iommu/vt-d: Remove use of private data field

"Private Data" field has been removed from Page Request/Response in
Intel VT-d specification revision 4.0.

Since the private data field has been removed, it's fine to remove the
entire private data handling from the driver as the specification
has been deprecated and Intel hasn't shipped any products which
support private data in the page request message.
