Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-5.0-20191217' into staging

ppc patch queue 2019-12-17

This is the first pull request for the qemu-5.0 branch.  It has a lot
of accumulated changes, including:

    * SLOF update to support boot using the IOMMU (will become
      necessary for secure guests)

    * Clean ups to pnv handling of chip models

    * A number of extensions to the powernv machine model

    * TCG extensions to allow powernv emulated systems to run KVM guests

    * Outline support for POWER10 chips in powernv

    * Cleanups to the ibm,client-architecture-support feature negotiation path

    * XIVE reworks to better handle the powernv machine

    * Improvements to not waste interrupt queues and other semi-scarce
      resources when using XIVE under KVM
