Like the jailhouse hypervisor, s390's PCI architecture allows passing isolated PCI functions to a guest OS instance. As of now this is was not utilized even with multi-function support as the s390 PCI code makes sure that only virtual PCI busses including a function with devfn 0 are presented to the PCI subsystem. A subsequent change will remove this restriction. Allow probing such functions by replacing the existing check for jailhouse_paravirt() with a new hypervisor_isolated_pci_functions() helper.
