minipack3n: Initial config for fan_service
Browse files Browse the repository at this point in the history 
Summary:
Add fan_service.json for the minipack3n fan_service.

**Description**
- Set the default fan speed to 60 percent before the thermal policy takes effect.
- This configuration has been tested on minipack3n.

**Test Plan**
- Run the fan_service with this configuration on minipack3n.
- Verify that the PWM is programmed to 60 percent.
