Subject: PCI: Enable PCI_DOMAINS along with generic PCI host controller

Git-commit: 37bd62d224c8244bccdb1a5bd7833a48c9ba8a66
Patch-mainline: v4.18-rc1
References: fate#326572

The generic PCI host controller is often instantiated by hypervisors, and
they may add several of them or add them in addition to a physical host
controller like the Jailhouse hypervisor is doing.  Therefore, allow for
multiple domains so that we can handle them all.
