Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.13-20180427' into staging

ppc patch queue 2018-04-27

Here's the first batch of ppc patches for 2.13.  This has a lot of
stuff that's accumulated during the 2.12 freeze.  Highlights are:

    * Many improvements for the Uninorth PCI host bridge for Mac
      machine types
    * Preliminary helpers improve handling of multiple backing
      pagesizes (not strictly ppc related, but have acks and aimed to
      allow future ppc changes)
    * Cleanups to pseries cpu initialization
    * Cleanups to hash64 MMU handling
    * Assorted bugfixes and improvements
