rcu: Remove debugfs tracing
RCU's debugfs tracing used to be the only reasonable low-level debug information available, but ftrace and event tracing has since surpassed the RCU debugfs level of usefulness. This commit therefore removes RCU's debugfs tracing. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

- This option provides tracing in RCU which presents stats
- in debugfs for debugging RCU implementation. It also enables
- additional tracepoints for ftrace-style event tracing.

Say Y here if you want to enable RCU tracing
Say N if you are unsure.
