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

6cf57be ("PCI: Add pcie_get_speed_cap() to find max supported link
speed") and c70b65f ("PCI: Add pcie_get_width_cap() to find max
supported link width") added declarations to drivers/pci/pci.h.

576c721 ("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.
