[PATCH linux dev-5.8] ARM: dts: aspeed: rainier: Enable fan watchdog

[Matthew Barth]

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
time the BMC stops pulsing the circuit, such as during a BMC reboot at
runtime.
