spapr_events: re-use EPOW event infrastructure for hotplug events
This extends the data structures currently used to report EPOW events to guests via the check-exception RTAS interfaces to also include event types for hotplug/unplug events. This is currently undocumented and being finalized for inclusion in PAPR specification, but we implement this here as an extension for guest userspace tools to implement (existing guest kernels simply log these events via a sysfs interface that's read by rtas_errd, and current versions of rtas_errd/powerpc-utils already support the use of this mechanism for initiating hotplug operations). We also add support for queues of pending RTAS events, since in the case of hotplug there's chance for multiple events being in-flight at any point in time.
