[PATCH 1/2] dt-bindings: connector: Add time property for tSenderResponse

[Amit Sunil Dhamne via B4 Relay]

From: Amit Sunil Dhamne <amitsd@xxxxxxxxxx>

Add the sender-response-time-ms property to allow platforms to specify
the tSenderResponse timer value, i.e. the max time a port waits for the
port partner to respond to a message that requires a response.

Also update the max33359 example to showcase the new property.
