meta-ampere: mtjade: support FAN fault check

Support FAN fault check via by enabling phosphor-led-manager's
monitor-operational-status with appropriate
phosphor-inventory-manager associations configuration.

Tested:
1. Get Led group list
   $ busctl tree xyz.openbmc_project.LED.GroupManager
   `- /xyz
  `- /xyz/openbmc_project
    `- /xyz/openbmc_project/led
      `- /xyz/openbmc_project/led/groups
        |- /xyz/openbmc_project/led/groups/fan_fault
2. Change the fan pwm, then stop the fan control service and verify
   that fault led is on
3. Start the fan control service and verify that fault led is off
