dt-bindings: usb: dwc3: Add Tx De-emphasis constraints



In accordance with the driver comments the PIPE3 de-emphasis can be tuned
to be either -6dB, -2.5dB or disabled. Let's add the de-emphasis
property constraints so the DT schema would make sure the controller DT
node is equipped with correct value.
