It was there for other hypervisor support, although XenGT support was
never upstream, but there's also some third-party hypervisor using GVT
device model.

For vGPU type, it planned to be used for XenGT as well, but it turned
out not to be true, yeah, I agree that should be in kvmgt.c and mdev only.
Thanks to point out this. Until to clean up this, I may pick this one first.
