After change, when CONFIG_PM_NDOMAINS > 1, the pm_register will not able to get notificaion from not PM_IDLE_DOMAIN. Should use pm_domain_register as a replacement. Isolate domains from global callbacks can decrease not necessary execution, and reduce the lock instruction requirements. Signed-off-by: buxiasen <buxiasen@xiaomi.com>
