drm/i915: cleanup pipe_update trace functions with new crtc debug info v3

Use the new debug info in the intel_crtc struct in these functions
rather than passing them as args.

v2: move min/max assignment back above first trace call (Ville)
    use scanline from crtc->debug rather than fetching a new one (Ville)
v3: fix up trace_i915_pipe_update_end, needs end scanline (Ville)
