PM / QoS: Add dev_pm_qos_request tracepoints
Adds tracepoints to dev_pm_qos_add_request, dev_pm_qos_update_request, and dev_pm_qos_remove_request. It's useful for checking device name, dev_pm_qos_request_type, and value. Signed-off-by: Sahara <keun-o.park@windriver.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
