PM / QoS: Add pm_qos_update_target/flags tracepoints
This patch adds tracepoints to pm_qos_update_target and pm_qos_update_flags. It's useful for checking pm qos action, previous value and current value. Signed-off-by: Sahara <keun-o.park@windriver.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
