From: Steven Rostedt <rostedt@goodmis.org>

The events device_pm_callback_start and device_pm_callback_end events are
only called when CONFIG_PM_SLEEP is defined. As each event can take up to
5K regardless if they are used or not, it's best not to define them when
they are not used. Add #ifdef around these events when they are not used.
