This state transition is entered when standby is requested
and an authenticated POD is present. When in semi-
standby, the CEservices will set the POD standby NVM
bit and ask infra to reboot. After the reboot, POD standby
will be entered. The Trimedia images are not started in
this case and CEsvc will ask infra to enter the Hardware
POD standby state.
