Tina Zhang 95925b9595 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. (Zhenyu)
