thunderbolt: Convert switch to a device Thunderbolt domain consists of switches that are connected to each other, forming a bus. This will convert each switch into a real Linux device structure and adds them to the domain. The advantage here is that we get all the goodies from the driver core, like reference counting and sysfs hierarchy for free. Also expose device identification information to the userspace via new sysfs attributes. In order to support internal connection manager (ICM) we separate switch configuration into its own function (tb_switch_configure()) which is only called by the existing native connection manager implementation used on Macs.
