ppc patch queue 2019-04-26

Here's the first ppc target pull request for qemu-4.1.  This has a
number of things that have accumulated while qemu-4.0 was frozen.

 * A number of emulated MMU improvements from Ben Herrenschmidt

 * Assorted cleanups fro Greg Kurz

 * A large set of mostly mechanical cleanups from me to make target/ppc
   much closer to compliant with the modern coding style

 * Support for passthrough of NVIDIA GPUs using NVLink2

As well as some other assorted fixes.
