[PATCH v4 0/2] refine VM engine reset

[Weinan Li]

GVT-g should just reset the execlist state of the engine which trigger
reset from VM. First refine the intel_vgpu_submission_ops as per engine
ops, then only reset execlist state of one engine during VM engine reset.
Otherwise VM may keep wrong execlist state and be inconsistent with vreg in
host.

  drm/i915/gvt: only reset execlist state of one engine during VM engine
