Merge remote-tracking branch 'remotes/dg-gitlab/tags/ppc-for-6.0-20210119' into staging

ppc patch queue 2021-01-19

Next pull request for qemu-6.0.  Not a huge amount here, but it does
have some important fixes from Greg Kurz.  Includes:

 * A number of minor cleanups from Daniel Barboza (preliminaries for
   some hotplug changes that are still under review)
 * Improved handling of memory hotplug from Greg Kurz
 * A number of fixes for sam460ex and other 440 based platforms from
   Zolan Balaton
 * Some fixes for the QOMification of the PPC 4xx UIC interrupt
   controller from Peter Maydell
