Subject[PATCH] drm/i915: Convert some trace events to DEFINE_TRACE
Use DECLARE_EVENT_CLASS to remove duplicate code:

text data bss dec hex filename
14655 2732 15 17402 43fa i915_trace_points.o.orig
11625 2732 10 14367 381f i915_trace_points.o

8 events are converted:

i915_gem_object: i915_gem_object_{unbind, destroy}
i915_gem_request: i915_gem_request_{complete, retire, wait_begin, wait_end}
i915_ring: i915_ring_{wait_begin, wait_end}

No functional change.
