PCI: Enable PCI_DOMAINS along with generic PCI host controller

Browse Source

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.

Say Y here if you want to support a simple generic PCI host
controller, such as the one emulated by kvmtool.
