I'm thinking it makes more sense to create the trace.h file inside the
drivers/irqchip/ directory. xfs does this, as well as other locations.

The include/trace/events/ was more of a generic method, but when events
start getting more specific, they should be in their own directories.

See samples/trace_events/* on how to have the file locally (or look at
xfs, search for trace in fs/xfs/Makefile).
