watchdog: wdat_wdt: Stop watchdog when rebooting the system
Executing reboot command several times on the machine "Dell PowerEdge R740", UEFI security detection stopped machine with the following prompt: UEFI0082: The system was reset due to a timeout from the watchdog timer. Check the System Event Log (SEL) or crash dumps from Operating Sysstem to identify the source that triggered the watchdog timer reset. Update the firmware or driver for the identified device. iDRAC has warning event: "The watchdog timer reset the system". This patch fixes this issue by adding the reboot notifier.
