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
   ...
   Mar 09 04:40:55 greatlakes swampd[2808]: Zone Id: 1
   Mar 09 04:40:55 greatlakes swampd[2808]: PID name:
   Stepwise_BB_INLET_TEMP_C
   Mar 09 04:40:55 greatlakes swampd[2808]: inputs: BB_INLET_TEMP_C,
   Mar 09 04:40:55 greatlakes swampd[2808]: PID name: fan0 1 2 3
   Mar 09 04:40:55 greatlakes swampd[2808]: inputs: BB_FAN0_TACH_RPM,
   BB_FAN1_TACH_RPM, BB_FAN2_TACH_RPM, BB_FAN3_TACH_RPM,
   Mar 09 04:40:55 greatlakes swampd[2808]: pushing zone 1
   Mar 09 04:40:55 greatlakes swampd[2808]: PID Zone 1 max SetPoint 70
   requested by Stepwise_BB_INLET_TEMP_C BB_FAN0_TACH_RPM
   BB_FAN1_TACH_RPM BB_FAN2_TACH_RPM BB_FAN3_TACH_RPM

2. Check fan PWM was set to 70%.
   root@greatlakes:~# busctl get-property \
   xyz.openbmc_project.FanSensor \
   /xyz/openbmc_project/sensors/fan_pwm/Pwm_1 \
   xyz.openbmc_project.Sensor.Value Value
   d 69.8039

   root@greatlakes:~# busctl get-property \
   xyz.openbmc_project.FanSensor \
   /xyz/openbmc_project/sensors/fan_pwm/Pwm_2 \
   xyz.openbmc_project.Sensor.Value Value
   d 69.8039

   root@greatlakes:~# busctl get-property \
   xyz.openbmc_project.FanSensor \
   /xyz/openbmc_project/sensors/fan_pwm/Pwm_3 \
   xyz.openbmc_project.Sensor.Value Value
   d 69.8039

   root@greatlakes:~# busctl get-property \
   xyz.openbmc_project.FanSensor \
   /xyz/openbmc_project/sensors/fan_pwm/Pwm_4 \
   xyz.openbmc_project.Sensor.Value Value
   d 69.8039
