[F][PATCH 0/11] Allow to reset an opencapi adapter (LP: 1862121)

IBM added code in firmware to allow to reset an opencapi adapter on a powerpc system, and retrain the opencapi link.
However, on linux, resetting the opencapi link is re-using the existing PCI hotplug framework,
but there's a bit of enablement code missing that is addressed here and should be added to Ubuntu 20.04, since it's a LTS release.
