XIVE2 has the concepts of a Group of interrupts and a Crowd of interrupts
(where a crowd is a group of Groups). These patch sets are associated with:
 - NVGC tables
 - Group/Crowd level notification
 - Incrementing backlog countets
 - Backlog processing
 - NVPG and NVC Bar MMIO operations
 - Group/Crowd testing
 - ESB Escalation
 - Pool interrupt testing
