spapr: Support hotplug by specifying DRC count
Support hotplug identifier type RTAS_LOG_V6_HP_ID_DRC_COUNT that allows
hotplugging of DRCs by specifying the DRC count.
While we are here, rename
spapr_hotplug_req_add_event() to spapr_hotplug_req_add_by_index()
spapr_hotplug_req_remove_event() to spapr_hotplug_req_remove_by_index()
so that they match with spapr_hotplug_req_add_by_count().
