meta-romulus: Add ipmi configs

Add ipmi configs for Romulus, where:
* cipher_list.json and dcmi_cap.json are the same as Witherspoon;
* dcmi_sensors.json is specific for Romulus, and the cpu core
  temperature configs are generated by sensor_yaml_config.py tool:
      sensor_yaml_config.py -i config.yaml -o output.json -d
*  dev_id.json is comes from Witherspoon, but manufacture the product id
   is left as 0, since Romulus is just a reference platform.

Tested: Verify ipmitool dcmi commands work ok on Romulus
