thunderbolt: Rework capability handling
Organization of the capabilities in switches and ports is not so random after all. Rework the capability handling functionality so that it follows how capabilities are organized and provide two new functions (tb_switch_find_vse_cap() and tb_port_find_cap()) which can be used to extract capabilities for ports and switches. Then convert the current users over these.
