PCI: Add pci_speed_string()
Add pci_speed_string() to return a text description of the supplied bus or
link speed. The slot code previously used the private
pci_bus_speed_strings[] array for this purpose, but adding this interface
will enable us to consolidate similar code elsewhere.
Export pcie_link_speed[] and pci_speed_string() so they can be used by
modules.
