    PCI: Drop duplicate pcie_get_speed_cap(), pcie_get_width_cap() declarations

    6cf57be0 ("PCI: Add pcie_get_speed_cap() to find max supported link
    speed") and c70b65fb ("PCI: Add pcie_get_width_cap() to find max
    supported link width") added declarations to drivers/pci/pci.h.

    576c7218 ("PCI: Export pcie_get_speed_cap and pcie_get_width_cap")
    subsequently added duplicates to include/linux/pci.h.

    Remove the originals from drivers/pci/pci.h.  Both interfaces are used by
    amdgpu, so they must be in include/linux/pci.h.
