I still think it's better to leave it in the watchdog driver: This
driver attaches to the watchdog device, and adding a separate driver
for reset means we have to trick the core Linux code into attaching
two drivers to one device in some way, or the device tree has to fake
a second device that doesn't exist in hardware but is only needed
because of Linux implementation details.
