[PATCH v4 00/15] genirq/msi: Silence set affinity failed warning

[Marek Vasut]

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.
