Support PCI adapter interrupts using the Single-IRQ-mode. Single-IRQ-mode disables an adapter IRQ automatically after delivering it until the SIC instruction enables it again. This is used to reduce the number of IRQs for streaming workloads. Up to 64 MSI handlers can be registered per PCI function. A hash table is used to map interrupt numbers to MSI descriptors. The interrupt vector is scanned using the flogr instruction. Only MSI/MSI-X interrupts are supported, no legacy INTs.
