mb/lenovo/t430s: Open PCIe port #5 for Thunderbolt controller
Some T430s variants has a Thunderbolt controller wired to PCIe
port #5, so it had better be left on for T430s. (T431s do not have
that)
The controller hotplugs itself to the chipset when a downstream device
is hotplugged into it, so the hotplug capability should be enabled on
PCIe port #5.
