drm/i915/skl: Update watermarks for Y tiling
Display watermarks need different programming for different tiling modes. Set the relevant flag so this happens during the plane commit and add relevant data into a structure made available to the watermark computation code. v2: Pass in tiling info to sprite plane updates as well. v3: Rebased for plane handling changes. v4: Handle fb == NULL when plane is disabled. v5: Refactored for addfb2 interface. v6: Refactored for fb modifier changes. v7: Updated for atomic commit by only updating watermarks when tiling changes. v8: BSpec watermark calculation updates. v9: Restrict scope of y_tile_minimum variable. (Damien Lespiau) v10: Get fb from plane state otherwise we are working on old state.
