[PATCH] tracing: Remove unused clock events

[Steven Rostedt]

From: Steven Rostedt (VMware) <rostedt@xxxxxxxxxxx>

Commit 74704ac6 ("tracing, perf: Add more power related events") added
new events, among them were trace_clock_enable, trace_clock_disable and
trace_clock_set_rate. In the last 7 years, nothing has used them. As
they take up space, and nobody cares about these events, remove them.
