Pull MSI updates from Thomas Gleixner:
 "Updates for the MSI interrupt subsystem and initial RISC-V MSI
  support.

  The core changes have been adopted from previous work which converted
  ARM[64] to the new per device MSI domain model, which was merged to
  support multiple MSI domain per device. The ARM[64] changes are being
  worked on too, but have not been ready yet. The core and platform-MSI
  changes have been split out to not hold up RISC-V and to avoid that
  RISC-V builds on the scheduled for removal interfaces.

  The core support provides new interfaces to handle wire to MSI bridges
  in a straight forward way and introduces new platform-MSI interfaces
  which are built on top of the per device MSI domain model.

  Once ARM[64] is converted over the old platform-MSI interfaces and the
  related ugliness in the MSI core code will be removed.

  The actual MSI parts for RISC-V were finalized late and have been
  post-poned for the next merge window.

  Drivers:

   - Add a new driver for the Andes hart-level interrupt controller

   - Rework the SiFive PLIC driver to prepare for MSI suport

   - Expand the RISC-V INTC driver to support the new RISC-V AIA
     controller which provides the basis for MSI on RISC-V

   - A few fixup for the fallout of the core changes"
