ppc/xive2: Support redistribution of group interrupts
When an XIVE context is pulled while it has an active, unacknowledged group interrupt, XIVE will check to see if a context on another thread can handle the interrupt and, if so, notify that context. If there are no contexts that can handle the interrupt, then the interrupt is added to a backlog and XIVE will attempt to escalate the interrupt, if configured to do so, allowing the higher privileged handler to activate a context that can handle the original interrupt.
