Merge tag 'devicetree-fixes-for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree fixes from Rob Herring:

 - a couple of DT node ref counting fixes

 - fix __unflatten_device_tree for PPC PCI hotplug case

 - rework marking irq controllers as OF_POPULATED in cases where real
   driver is used.

 - disable of_platform_default_populate_init on PPC.  The change in
   initcall order causes problems which need to be sorted out later.
