firmware: stratix10-svc: extend svc to support RSU feature
Extend Intel Stratix10 service layer driver to support new RSU
DCMF status reporting.
The status of each DCMF is reported. The currently used DCMF is used as
reference, while the other three are compared against it to determine if
they are corrupted.
DCMF = Decision Configuration Management Firmware
RSU = Remote System Update
