Various PCIe controllers that mux MSIs onto single IRQ line produce these "IRQ%d: set affinity failed" warnings when entering suspend. Remove the .irq_set_affinity callbacks and make sure they are NULL in all affected controllers, so this warning in kernel/irq/msi.c is not triggered. This has been compile-tested only on all but the R-Car PCI controller. The clean ups are done per-driver so they can be easily reverted in case they break something.
