    Pull MSI interrupt updates from Thomas Gleixner:
     "Switch ARM/ARM64 over to the modern per device MSI domains.
    
      This simplifies the handling of platform MSI and wire to MSI
      controllers and removes about 500 lines of legacy code.
    
      Aside of that it paves the way for ARM/ARM64 to utilize the dynamic
      allocation of PCI/MSI interrupts and to support the upcoming non
      standard IMS (Interrupt Message Store) mechanism on PCIe devices"
