drm/i915/gvt: Use KVM r/w to access guest opregion
For KVMGT, the guest opregion, which is handled by VFIO, is actually a piece of guest memory which won't be accessed by devices. So, its mfn shouldn't be obtained through VFIO interface. This patch uses KVM r/w interface to access the data in guest opregion. Fix the guest opregion accessing issue when host "intel_iommu=on". v3: - Remove mapped flag for KVM/VFIO usage, as it's useless for KVM. v2: - Set the gpa correctly when invoking KVM r/w operations.
