Bug description:
Description: s390/pci: Fix PCHID per port multi-function detection
Symptom: There are two cases in which PCI functions are incorrectly
placed, or not placed, in a shared PCI topology. In the first
case a PCI physical function (PF) which is initially in standby
was incorrectly not creating a new PCI topology when
hotplugged,
but would if configured during boot. In the second case a PCI
virtual function (VF) would be placed in the shared PCI
topology
of a PF if that PF is from the same card even if the parent PF
is not in the configuration which should lead the VF to be
isolated in its own single function topology.
Problem: Both problems are caused by logic bugs in the determination of
which PCI functions create topologies and when a PCI function
may be added to an existing topology.
