Subject: [PATCH] documentation: Add links to TRACE_EVENT documentation

documentation: Add links to TRACE_EVENT documentation

Existing tracepoint documentation doesn't mention the popular
TRACE_EVENT
macro. Since an excellent series of articles on proper usage already
exists, respective links are added to the existing documentation.
