PM / Domains: Introduce function to power off all unused PM domains
Add a new function pm_genpd_poweroff_unused() queuing up the execution of pm_genpd_poweroff() for every initialized generic PM domain. Calling it will cause every generic PM domain without devices in use to be powered off. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>
