PCI: Make resetting secondary bus logic common
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. To avoid the duplication, move the logic to pci_reset_secondary_bus(). That commit did not declare the pcibios_reset_secondary_bus() interface in linux/include/pci.h. Add the declaration. No functional change. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
