drm/i915: Simplify watermark state checker calling convention

There is never any reason to pass in both the crtc and its state
as one can always dig out the crtc from its state. But for more
consistency across the whole state checker let's just pass the
overall atomic state+crtc here as well.

v2: Also pass state+crtc here (Jani)
