Artemis: cb: Support FIO Present LOG (#1355)

Summary:
# Description:
  - As title.

 # Motivation:
 - To Support FIO present LOG

Pull Request resolved: #1355

Test Plan:
- Builr pass and FIO present/not Present LOG can be logged. - pass

 # Log:
 - Present ``` root@bmc-oob:~# log-util --print all | grep FIO
0    all      2018-03-09 04:35:58    pldmd            State Sensor: CB_SENSOR_FIO, present
root@bmc-oob:~#
 ```
 - Not Present
 ```
 root@bmc-oob:~# log-util --print all | grep FIO
0    all      2018-03-09 04:35:58    pldmd            State Sensor: CB_SENSOR_FIO, not present
