[POWERPC] spufs: Add marker-based tracing facility
This adds markers two important points in the spufs code and a new module (sputrace.ko) that allows reading these out through a proc file. Long-term I'd rather see something like lttng extended to use the spufs instrumentation, but for now I think this is a good enough quick solution. We'll probably want to add various addition event in addition to that ones I have already.
