  Zero hops in tb_path_activate before writing a new path.

  This fixes the following scenario:
  - Boot with a coldplugged device
  - Unplug device
  - Plug device back in
  - PCI hotplug fails

  The hotplug operation fails because our new path matches the (now
  defunct) path which was setup by the firmware for the coldplugged
  device. By writing zeros before writing our path configuration we can
  force thunderbolt to retrain the path.

  A thunderbolt path is a unidirectional channel between two thunderbolt
  ports. Two such paths are needed to establish a pci tunnel.

  This patch introduces struct tb_path as well as a set of tb_path_*
  methods which are used to activate & deactivate paths.
