Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-3.1-20180821' into staging

ppc patch queue 2018-08-21

Here's my first ppc & spapr pull request for qemu-3.1.  This contains
a bunch of things that have accumulated while 3.0 was in freeze.
Highlights are:
    * SLOF firmware update
    * A number of floating point cleanups from Richard Henderson and
      Yasmin Beatriz
    * A new model for assigning irq numbers on spapr, this is an
      important preliminary step towards implementing the POWER9
      "XIVE" interrupt controller
