thunderbolt: Introduce tb_switch_downstream_port()
Introduce tb_switch_downstream_port() helper function that returns the
downstream port of a parent switch that is connected to the upstream
port of specified switch. From now on, we use it all across the driver
where applicable.
While there fix a whitespace in comment and rename 'downstream' to
'down' to be consistent with the rest of the driver.
