vgt_caps is used for guest i915 driver to get the vgpu capabilities from
the device model. VGT_CPAS_FULL_PPGTT is one of the capabilities type to
let guest i915 dirver know that the guest i915 full ppgtt is supported by
device model.
Changes since v1:
- Use u32 instead of uint32_t (Joonas)
- Move VGT_CAPS_FULL_PPGTT introduction to this patch and use #define instead
of enum (Joonas)
