meta-facebook: greatlakes: add draft fan table
Description:
- Add draft fan table for Great Lakes.
- Will set all PWMs to 70%.
Design:
- Add draft fan table to the default path for phosphor-pid-control
service.
Test Case:
1. Check status of phosphor-pid-control service.
root@greatlakes:~# systemctl status phosphor-pid-control -l
