The generic PM domains core code currently requires domains to be in the "power on" state for adding devices to them, but this limitation turns out to be inconvenient in some situations, so remove it. For this purpose, make __pm_genpd_add_device() set the device's need_restore flag if the domain is in the "power off" state, so that the device's "restore state" (usually .runtime_resume()) callback is executed when it is resumed after the domain has been turned on. If the domain is in the "power on" state, the device's need_restore flag will be cleared by __pm_genpd_add_device(), so that its "save state" (usually .runtime_suspend()) callback is executed when the domain is about to be turned off. However, since that default behavior need not be always desirable, add a helper function pm_genpd_dev_need_restore() allowing a device's need_restore flag to be set/unset at any time.
