Backport and enable the Realtek Otto watchdog driver for enhanced system reliability. The watchdog driver can also be used to restart the system, but that requires the _machine_restart to be removed. Removing _machine_restart has the added benefit of enabling the use of other restart handlers in addition to the watchdog restart, such as gpio-restart, which may be more reliable than the SoCs internal reset circuitry. Removing the override also brings the current target closer to upstream, which will become relevant when switching to the next LTS kernel. This series contains the watchdog driver as currently submitted upstream, without the devicetree bindings. If the driver gets accepted before this series is merged, I can already update it with the final version. Otherwise, a follow-up will be sent to replace the patch. The WDT driver was previously tested on my Netgear GS110TPPv1, Zyxel GS1900-8, and Zyxel XGS1250-12. Testers with other devices should ensure that their system can still restart after applying the complete series.
