automatic interrupt affinity for MSI/MSI-X capable devices V3

This series enhances the irq and PCI code to allow spreading around MSI and MSI-X vectors so that they have per-cpu affinity if possible, or at least per-node. For that it takes the algorithm from blk-mq, moves it to a common place, and makes it available through a vastly simplified PCI interrupt
