PM-runtime: Consolidate code to get active/suspended time
In a step to consolidate the code for fetching the PM-runtime active/suspended time for a device, add a common function for that and make the existing pm_runtime_suspended_time() call it. Also add a corresponding pm_runtime_active_time() calling the new common function. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> [ rjw: Changelog, function rename ] Signed-off-by: Rafael J.
