nyan*: Detect watchdog resets and reset the whole machine.
When a watchdog reset happens, the SOC will reset but other parts of the system might not. That puts the machine in a funny state and may prevent it from booting properly. BUG=chrome-os-partner:28559 TEST=Built for nyan, nyan_big and nyan_blaze. Booted normally, through EC reset, software reset ("reboot" command from the terminal), and through watch dog reset. Verified that the new code only triggered during the watchdog reset and that the system rebooted and was able to boot without going into recovery mode unnecessarily.
