drm/i915/tc: Fix target TC mode for a disconnected legacy port

Browse source

Atm, the target TC mode - which the PHY should be switched to at any
point it's used - is TBT in case there is no sink connected. However
legacy ports are only used in the legacy mode regardless of the sink
connected state. Fix the mode returned by
intel_tc_port_get_target_mode() accordingly.

Despite of the above issue, the PHY got disconnected as expected in
response to a sink disconnect event, causing only a redundant
PHY disconnect->reconnect sequence whenever the port was used.
