Public bug reported: [Impact]
When the SBSA watchdog runs from boot, it remains armed without refresh during early suspend entry and late resume. A slow device callback can therefore reset the system during the transition. [Fix] Stop the watchdog from a PM notifier at the suspend prepare events and restart it at the post-suspend events, retaining the device PM callbacks as an idempotent fallback.
