After you introduce some flags for controller to decide if HNP/SRP/ADP can be
supported, this setting in all gadget drivers should be override according to those
flags too, otherwise there will be possible mismatch between the OTG descriptor
within config(like above setting) and the response for getting OTG descriptor
request(your patch 3 does in composite.c).
