watchdog: rti_wdt: Drop runtime pm reference count when watchdog is unused
Call runtime_pm_put*() if watchdog is not already started during probe and re
enable it in watchdog start as required.
On K3 SoCs, watchdogs and their corresponding CPUs are under same
power-domain, so if the reference count of unused watchdogs aren't
dropped, it will lead to CPU hotplug failures as Device Management
firmware won't allow to turn off the power-domain due to dangling
reference count.
