drm/i915: Add pipe enable/disable tracepoints

Browse source

Add tracepoints for pipe enable/disable. We'll include the
frame/scanline counters for all pipes in these tracepoints to
help in diagnosing underruns and whatnot when enabling/disabling
pipes in parallel with plane updates/flips on another pipe.
