Many of the struct fields can be generic and don't have to be type specific like hpet_id, ioapic_id... Provide a generic set of members to prepare for the consolidation. The goal is to make irq_alloc_info have the same basic member as the generic msi_alloc_info so generic MSI domain ops can be reused and yet more mess can be avoided when (non-PCI) device MSI support comes along.
