Xen devel - Sep 2010 - [PATCH][VTD] fix vt-d feature boot messages

Changed vt-d feature boot messages from "supported" to
"enabled" since they reflect what is currently enabled in this Xen
boot - not what is supported by VT-d hardware.  Also, changed reference to
"VT-d DMA Passthrough" to "VT-d Passthrough in Context
Entry" to make it less alarming to the reader.

Is that "make less alarming by obfuscation"? It *is* DMA passthrough,
although it would be worth noting in the message that it is for dom0 only.

Admittedly, "DMA Passthrough" is the official name is VT-d spec. 
Unfortunately, this overloads "passthrough" with two different
meanings.  (1) direct assignment and (2) VT-d translation passthrough.

Numerous people has asked about this message whenever VT-d does not work for
them - thinking device assignment is not enabled.
