Add infrastructure for sending setSystemConfig cmd to SBE

The SBE needs to know about other PROCs in the sytem. To do
this we are sending a 64 bit string that encodes the system
configuration down to the SBE at the end of the IPL. This
commit just sets up some of the infrastructure that will be needed
to send the message.
