ppc patch queue 2019-07-2

Here's my next pull request for qemu-4.1.  I'm not sure if this will
squeak in just before the soft freeze, or just after.  I don't think
it really matters - most of this is bugfixes anyway.  There's some
cleanups which aren't stictly bugfixes, but which I think are safe
enough improvements to go in the soft freeze.  There's no true feature
work.

Unfortunately, I wasn't able to complete a few of my standard battery
of pre-pull tests, due to some failures that appear to also be in
master.  I'm hoping that hasn't missed anything important in here.

Highlights are:
  * A number of fixe and cleanups for the XIVE implementation
  * Cleanups to the XICS interrupt controller to fit better with the new
    XIVE code
  * Numerous fixes and improvements to TCG handling of ppc vector
    instructions
  * Remove a number of unnnecessary #ifdef CONFIG_KVM guards
  * Fix some errors in the PCI hotplug paths
  * Assorted other fixes
