greybus: es2: add define for ARPC CPort requests

Add dedicated define for ARPC CPort requests instead of using the default timeout for USB vendor requests. We still allow responses to take 500 ms to arrive, but note that this adds on top of the 500ms already allowed for a requests to be acknowledged. This should probably be tightened up at some point.
