fp5280g2: Enable TFTP updates via Redfish

TFTP is already support within bmcweb via Redfish and by default that
was disabled. We need to enable it by default on fp5280g2 machine

Testd: Updated successfully via the following Redfish
curl -k -H "X-Auth-Token: $token" -X POST
https://${bmc}/redfish/v1/UpdateService/Actions/UpdateService.SimpleUpdate
-d
'{"TransferProtocol":"TFTP","ImageURI":"<ip address of TFTP server>/obmc-phosphor-image-fp5280g2-20190924042243.static.mtd.tar"}'
