Subject: Add Asset information for FabricAdapter

This commit is to add asset information according to the Redfish
FabricAdapter schema. If the
`xyz.openbmc_project.Inventory.Decorator.Asset` interface does not
exist, the asset information property is not displayed.

ref: http://redfish.dmtf.org/schemas/v1/FabricAdapter.v1_4_0.json

Tested: Validator passes #
```
curl -k https://$bmc:/redfish/v1/Systems/system/FabricAdapters/disk_backplane0
{
  "@odata.id": "/redfish/v1/Systems/system/FabricAdapters/disk_backplane0",
  "@odata.type": "#FabricAdapter.v1_4_0.FabricAdapter",
  "Id": "disk_backplane0",
  "Location": {
    "PartLocation": {
      "ServiceLabel": "U78DA.ND0.WZS0042-P1"
    }
  },
  "Model": "6B89",
  "Name": "Fabric Adapter",
  "PartNumber": "02WG682",
  "SerialNumber": "YA31UF09P002",
  "SparePartNumber": "02WG681"
}
