HW running watchdogs are just watchdogs that are enabled before the
Linux driver is probed, usually by the bootloader (eg. U-Boot).

When the system is shutting down, the mechanism for keeping a HW running
watchdog pinged is also stopped, but the watchdog itself is not stopped,
causing a reset, and preventing the system from being shut down.

Opt into stopping watchdogs on reboot.
