Patch 1-2: mostly for debugging purpose, either on continuous
           converting tracepoints into error reports, or fix incorrect
           debug messages.

Patch 3:   enable dma read/write draining support for vt-d emulation.
           The major reason is to pass Windows SVVP verification.

Patch 4-5: some tunes on existing VT-d parameters, either name or
           default value.  This turns IR on by default for 4.0 or later.

Please review.  Thanks.
