ppc/xics: extend the QOM interface to handle ICPs
Let's add two new handlers for ICPs. One is to get an ICP object from a server number and a second is to resend the irqs when needed. The icp_resend() handler is a temporary workaround needed by the ics-simple post_load() handler. It will be removed when the post_load portion can be done at the machine level.
