tracing: Add ftrace_event_call void * 'data' field
add an optional void * pointer to 'ftrace_event_call' that is passed in for regfunc and unregfunc. This prepares for syscall tracepoints creation by passing the name of the syscall we want to trace and then retrieve its number through our arch syscall table.
