Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-4.0-20190204' into staging

ppc patch queue 2019-02-04

Here's the next batch of ppc target and spapr related changes.
Highlights are:
 * A number of endianness handling cleanups from Mark Cave-Ayland
 * Updated Mac VGA driver
 * Updated SLOF image
 * Some XIVE cleanups and small fixes
 * ppc4xx cleanups and fixes from BALATON Zoltan

There are a few chances not technically in the ppc target code:
 * Several MAINTAINERS updates
 * Fixes for unmapping of hugepages on power hosts

The latter is included because it's primarily of interest for ppc KVM setups.
