Limitting the WM levels to 0 for DG2 during async flips,
allows to slightly increase the perfomance, as recommended
by HW team.

Stanislav Lisovskiy (4):
  drm/i915: Pass plane to watermark calculation functions
  drm/i915: Introduce do_async_flip flag to intel_plane_state
  drm/i915: Use wm0 only during async flips for DG2
  drm/i915: Don't allocate extra ddb during async flip for DG2
