meta-romulus: phosphor-hwmon workaround for fan speed
Romulus uses aspeed pwm and fan tacho, and its driver returns ETIMEDOUT
for fan speed when host is off, which causes phosphor-hwmon exit with
excpetion for fan_tacho sensors.
The workaround is to handle ETIMEDOUT and make it return -ETIMEDOUT
value for the sensor.
