PM / Domains: Check domain status during hibernation restore of devices
Power domains that were off before hibernation shouldn't be turned on during device restore, so prevent that from happening. This change fixes up commit 65533bbf63b4f37723fdfedc73d0653958973323 PM / Domains: Fix hibernation restore of devices, v2 that didn't include it by mistake. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
