Subject: Add interface to look up model type of master processor on
 targetService

While going through IPL flow updates for Axone I realized it would be
handy to have a targetService utility function that told us what MODEL
we are running hostboot for. This commit introduced the interface
TargetService::getProcessorModel() which will return the model of the
master processor.
