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.
