Suspend routine disables wdog clk. Nevertheless, the watchdog subsystem is not aware of that and can still try to ping wdog through watchdog_ping_work. In order to prevent such condition and therefore prevent from system hang (caused by the wdog register access issued while the wdog clock is disabled) notify watchdog core that the ping worker should be canceled during watchdog core suspend and restored during resume.
