According to Intel VT-d specification revision 4.0, "Private Data"
field has been removed from Page Request/Response.
Since the private data field is not used in fault message, remove the
related definitions in page request descriptor and remove the related
code in page request/response handler, as Intel hasn't shipped any
products which support private data in the page request message.
