The VT-d spec Revision 3.3 updated the virtual command registers, virtual
command opcode B register, virtual command response register and virtual
command capability register (Section 10.4.43, 10.4.44, 10.4.45, 10.4.46).
This updates the virtual command interface implementation in the Intel
IOMMU driver accordingly.
