- Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a single IRQ
  line and cannot set the affinity of each MSI to a specific CPU core
  (Marek Vasut)

- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
  implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
  mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl, xilinx-xdma, and
  xilinx drivers to avoid "IRQ: set affinity failed" warnings (Marek Vasut)
