PM / Runtime: Add new helper function: pm_runtime_status_suspended()
This boolean function simply returns whether or not the runtime status of the device is 'suspended'. Unlike pm_runtime_suspended(), this function returns the runtime status whether or not runtime PM for the device has been disabled or not. Also add entry to Documentation/power/runtime.txt Signed-off-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
