mb/lenovo/t430s: Open PCIe port #5 for Thunderbolt controller
Some T430s variants have a Thunderbolt controller wired to PCIe port 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. TODO: find the correct gpio pin to detect the Thunderbolt controller at runtime. There are 3 variants of mainboard for Thinkpad T430s: Basic type (Wistron LSN-4 11263-1), Boards with an additional discreet GPU, Boards with an additional TB controller (Wistron LSN-4 11271-1), each of which has a different schematic. The gpio27 on the last type is set as set as GPIO-INPUT, compared with GPIO-OUTPUT-HIGH on the basic type boards.
