Add a ports declaration which is optional containing two port@
declarations.
port@0 to receive an orientation-switch message from the Type-C port or
redriver
port@1 to subsequently transmit the orientation-switch on once the PHY has
finished doing its orientation turn-around.
If ports is declared the input port port@0 is mandatory but the output
port@1 is optional.
