ARM: dts: aspeed: rainier: Enable fan watchdog

Browse Source 
Set watchdog 1 to pulse the fan watchdog circuit that drives the FAULT
pin of the MAX31785, resulting in fans running at full speed, if at
any point the BMC stops pulsing it, such as a BMC reboot at runtime.
Enable watchdog 2 for BMC reboots.
