spapr_events: event-scan RTAS interface
We don't actually rely on this interface to surface hotplug events, and instead rely on the similar-but-interrupt-driven check-exception RTAS interface used for EPOW events. However, the existence of this interface is needed to ensure guest kernels initialize the event-reporting interfaces which will in turn be used by userspace tools to handle these events, so we implement this interface here. Since events surfaced by this call are mutually exclusive to those surfaced via check-exception, we also update the RTAS event queue code to accept a boolean to mark/filter for events accordingly. Events of this sort are not currently generated by QEMU, but the interface has been tested by surfacing hotplug events via event-scan in place of check-exception.
