drm/i915/gen9+: Program watermarks as a separate step during evasion, v3.
The watermark updates for SKL style watermarks are no longer done in the plane callbacks, but are now called in a separate watermark update function that's called during the same vblank evasion, before the plane updates. This also gets rid of the global skl_results, which was required for keeping track of the current atomic commit. Changes since v1: - Move line unwrap to correct patch. (Lyude) - Make sure we don't regress ILK watermarks. (Matt) - Rephrase commit message. (Matt) Changes since v2: - Fix disable watermark check to use the correct way to determine single step watermark support.
