drm/i915/gvt: vGPU PCI configuration space virtualization
This patch introduces vGPU PCI configuration space virtualization.
- Adjust the trapped GPFN(Guest Page Frame Number) window of virtual GEN
PCI BAR 0 when guest initializes PCI BAR 0 address.
- Emulate OpRegion when guest touches OpRegion.
- Pass-through a part of aperture to guest when guest initializes
aperture BAR.
