Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.12-20180111' into staging

ppc patch queue 2018-01-11

This pull request supersedes ppc-for-2.12-20180108 and several before
it.  The earlier pull request included a patch which exposed a bug in
the ARM TCG backend.  I've pulled that out and will repost once the
ARM bug is fixed (a patch has been posted by Richard Henderson).

Higlights from this series:
  * SLOF update
  * Several new devices for embedded platforms
  * Fix to correctly set compatiblity mode for hotplugged CPUs
  * dtc compile fix for older MacOS versions
