drm/i915: Calculate pipe watermarks into CRTC state (v3)
A future patch will calculate these during the atomic 'check' phase
rather than at WM programming time, so let's store the watermark
values we're planning to use in the CRTC state; the values actually
active on the hardware remains in intel_crtc.
While we're at it, do some minor restructuring to keep ILK and SKL
values in a union.
v2: Don't move cxsr_allowed to state (Maarten)
v3: Only calculate watermarks in state. Still keep active watermarks in
intel_crtc itself. (Ville)
