rcu: Remove debugfs tracing

Browse Source 
RCU's debugfs tracing used to be the only reasonable low-level debug

the RCU debugfs level of usefulness.  This commit therefore removes
RCU's debugfs tracing.

additional tracepoints for ftrace-style event tracing.

Say Y here if you want to enable RCU tracing
