firmware: stratix10-svc: extend svc to support new RSU features
Extend Intel Stratix10 service layer driver to support new RSU DCMF
versions and max retry parameter.
DCMF = Decision Configuration Management Firmware. The max retry parameter
is the maximum times the images is allowed to reload itself before giving
up and starting RSU failover flow.
