Subject: [PATCH 2/2] ftrace: Code cleanup for kernel/trace/trace_events_stage_*.h

Add TRACE_FORMAT's define for trace_events_stage_2.h.
Although it is already defined in trace_events_stage_1.h, we should make each
function independence.

Move TP_fast_assign's define from trace_events_stage_2.h to
trace_events_stage_3.h because it is used there.

Unify TRACE_EVENT's 5th argument's name to "assign"

Impact: cleanup, no functionality changed
