PCI: expose pcie_link_speed and pcix_bus_speed arrays
pcie_link_speed and pcix_bus_speed are arrays used by probe.c to correctly convert lnksta register values into the pci_bus_speed enum. These static arrays are useful outside probe for this purpose. This patch makes these defines into conist arrays and exposes them with an extern header in drivers/pci/pci.h -v2- * move extern declarations to drivers/pci/pci.h CC: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
