At least we need one MPT module (currently only have one) selected to get GVTg functional. When GVTg is enabled while no MPT selected, the build just includes useless GVTg code. This doesn't make sense.
The reason was that we tried to merge gvt device model in upstream first while finishing KVMGT part later. I'm ok with this now.
With this patch, a submenut is created under i915 as below: -*- Enable Intel GVT-g graphics virtualization host support <M> Enable KVM/VFIO support for Intel GVT-g
If no MPT is selected, GVTg will be disabled automatically. < > Enable KVM/VFIO support for Intel GVT-g
