[PATCH 15/19] drm/i915/tc: Handle non-TC encoders when getting the pin assignment

[Imre Deak]

For consistency, handle the case where
intel_tc_port_get_pin_assignment() is called for a non-TypeC encoder,
returning the default NONE pin assignment value, similarly to how this
is done in intel_tc_port_max_lane_count().
