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
