Lu Baolu 253bac6c60 iommu/vt-d: Update the virtual command related registers

[ Upstream commit 4d99efb229e63928c6b03a756a2e38cd4777fbe8 ]

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.
