We receive a plug event callback whenever a thunderbolt device is added
or removed. This patch fills in the tb_handle_hotplug method and starts
reacting to these events by adding/removing switches from the hierarchy.

switch allocation.

on pci devices. This patch introduces a tb_find_cap utility method to
search for capabilities.

Add struct tb which will contain our view of the thunderbolt bus. For
now it just contains a pointer to the control channel and a workqueue
for hotplug events.
Add thunderbolt_alloc_and_start() and thunderbolt_shutdown_and_free()
which are responsible for setup and teardown of struct tb.
