Wei Yang May 19, 2015, 1:35 a.m. UTC 
As commit ac205b7b ("PCI: make sriov work with hotplug remove") indicates,
VFs, which might be hooked to same PCI bus as their PF should be removed
before the PF. Otherwise, the PCI hot unplugging on the PCI bus would
cause kernel crash.

The patch applies the above pattern to PowerPC PCI hotplug path.
