Merge remote-tracking branch 'mst/tags/for_upstream' into staging
pci, virtio, vhost: fixes
A bunch of fixes that missed the release.
Most notably we are reverting shpc back to enabled by default state
as guests uses that as an indicator that hotplug is supported
(even though it's unused). Unfortunately we can't fix this
on the stable branch since that would break migration.
