Analogix 7625 can be used in systems to switch the DP traffic between two downstreams, which can be USB Type-C DisplayPort alternate mode lane or regular DisplayPort output ports.
Update the binding to accommodate this usage by introducing a data-lanes and a mode-switch property on endpoints. Also include the link to the product brief in the bindings.
