tracing: consolidate documents
Li Zefan [Thu, 9 Apr 2009 03:40:27 +0000 (11:40 +0800)]
Move kmemtrace.txt, tracepoints.txt, ftrace.txt and mmiotrace.txt to
the new trace/ directory.

I didnt find any references to those documents in both source
files and documents, so no extra work needs to be done.
