[net-next 08/15] pci: expose pcie_link_speed and pcix_bus_speed arrays

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Jacob Keller <jacob.e.keller@intel.com>

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
const arrays and exposes them with an extern header in linux/include/pci.h
