drm/i915: Calculate ironlake intermediate watermarks correctly, v2.
The watermarks it should calculate against are the old optimal watermarks. The currently active crtc watermarks are pure fiction, and are invalid in case of a nonblocking modeset, page flip enabling/disabling planes or any other reason. When the crtc is disabled or during a modeset the intermediate watermarks don't need to be programmed separately, and could be directly assigned to the optimal watermarks. Changes since v1: - Use intel_atomic_get_old_crtc_state.
