Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.10-20170630' into staging

ppc patch queue 2017-06-30

  * More DRC cleanups, these now actually fix a few bugs
  * Properly implements the openpic timers (they now count and
    generate interrupts)
  * Fixes for XICS migration
  * Fixes for migration of POWER9 RPT guests
  * The last of the compatibility mode rework
