Grzegorz Jaszczyk 8b9e62cf99 watchdog: introduce watchdog_dev_suspend/resume
The watchdog drivers often disable wdog clock during suspend and then
enable it again during resume. Nevertheless the ping worker is still
running and can issue low-level ping while the wdog clock is disabled
causing the system hang. To prevent such condition introduce
watchdog_dev_suspend/resume which can be used by any wdog driver and
actually cancel ping worker during suspend and restore it back, if
needed, during resume.
