PM / Runtime: Improve prepare handling at system suspend for genpd
When genpd prepares for a system suspend it will fetch a runtime reference for the device. When returning it we now use the asyncronous runtime PM API. Thus we don't have to wait for the device to become idle|suspended before we move on and handle the next device in queue. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Rafael J.
