Fix DC power-on and -off MessageId format

The MessageId format is
RegistryName.MajorVersion.MinorVersion.MessageKey.

This change adds the RegistryName.MajorVersion.MinorVersion
before the DC power-on and -off MessageKeys.

Tested:
Verified that the DCPowerOn and DCPowerOff Redfish Message
entries are correctly displayed in the Redfish event log.
