Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.8-20161017' into staging

ppc patch queue 2016-10-17

Highlights:
    * Significant rework of how PCI IO windows are placed for the
      pseries machine type
    * A number of extra tests added for ppc
    * Other tests clean up / fixed
    * Some cleanups to the XICS interrupt controller in preparation
      for the 'powernv' machine type

A number of the test changes aren't strictly in ppc related code, but
are included via my tree because they're primarily focused on
improving test coverage for ppc.
