Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-5.2-20201028' into staging

ppc patch queue 2020-10-28

Here's the next pull request for ppc and spapr related patches, which
should be the last things for soft freeze.  Includes:

 * Numerous error handling cleanups from Greg Kurz
 * Cleanups to cpu realization and hotplug handling from Greg Kurz
 * A handful of other small fixes and cleanups

This does include a change to pc_dimm_plug() that isn't in my normal
areas of concern.  That's there as a a prerequisite for ppc specific
changes, and has an ack from Igor.
