Commit d92a208d086 ("powerpc/pci: Mask linkDown on resetting PCI bus")
implemented same logic (resetting PCI secondary bus by bridge's config
register PCI_BRIDGE_CTL_BUS_RESET) in PCI core and arch-dependent
code. In order to avoid the duplicate implementation introduced by the
commit, the patch puts the logic into pci_reset_secondary_bus().
That commit also missed declaring newly introduced weak function
pcibios_reset_secondary_bus() in linux/include/pci.h. The patch fixes
it.

Since the logic to reset PCI secondary bus by PCI config register
PCI_BRIDGE_CTL_BUS_RESET is included in pci_reset_secondary_bus(),
we needn't implement another one of ourself. The patch removes the
duplicate implementation and calls pci_reset_secondary_bus().

I applied both of these to pci/virtualization for v3.17. Ben, if you'd
rather apply the powerpc one [1], let me know and I'll drop that one.

I'm happy for you to keep it. If for some reason I want it too we can
both carry it, it shouldn't hurt significantly at merge time.
