From: Rafael J. Wysocki <rafael.j.wyso...@intel.com>
The runtime PM documentation in runtime_pm.txt has not been updated
after some changes to the system suspend and resume core code, so
update it to reflect the current code flow.

This is independent of the "do not resume runtime-suspended devices" series.
Thanks!

out the following operations:
- * During system suspend it calls pm_runtime_get_noresume() and
