drm/i915/gvt: Factor out intel_vgpu_{get, put}_ppgtt_mm interface
Factor out these two interfaces so we can kill some duplicated code in scheduler.c. v2: - rename to intel_vgpu_{get,put}_ppgtt_mm - refine handle_g2v_notification Signed-off-by: Changbin Du <changbin.du@intel.com> Reviewed-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
