Subject: [net-next v2 08/15] PCI: expose pcie_link_speed and pcix_bus_speed arrays

From: Jacob Keller <jacob.e.keller@...el.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
conist arrays and exposes them with an extern header in drivers/pci/pci.h

-v2-
* move extern declarations to drivers/pci/pci.h
