In the Type-C graph, the nb7vpq904m retimer is in between the USB-C
connector and the USB3/DP combo PHY, and this PHY also requires the
USB-C mode events to properly set-up the SuperSpeed Lanes functions
to setup USB3-only, USB3 + DP Altmode or DP Altmode only on the 4 lanes.
Update the nb7vpq904m retimer to get an optional type-c mux on the next
endpoint, and broadcast the received mode to it.
