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
conist arrays and exposes them with an extern header in drivers/pci/pci.h

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

If you edit this patch to add my ack or for other reasons,
s/conist/const/ above.  The "-v2-" text doesn't need to be in the
changelog, so you can omit it completely, or put it after a line
containing only "---".  I also conventionally capitalize the first
word of the change summary ("Expose") here; run "git log --oneline
drivers/pci/" to see samples.

But don't respin these patches just for that :)
