ftrace: Remove use of control list and ops
Currently perf has its own list function within the ftrace infrastructure that seems to be used only to allow for it to have per-cpu disabling as well as a check to make sure that it's not called while RCU is not watching. It uses something called the "control_ops" which is used to iterate over ops under it with the control_list_func(). The problem is that this control_ops and control_list_func unnecessarily complicates the code. By replacing FTRACE_OPS_FL_CONTROL with two new flags (FTRACE_OPS_FL_RCU and FTRACE_OPS_FL_PER_CPU) we can remove all the code that is special with the control ops and add the needed checks within the generic ftrace_list_func().
