usb: gadget: add SuperSpeed support to the Gadget Framework
SuperSpeed USB has defined a new descriptor, called the Binary Device Object Store (BOS) Descriptor. It has also changed a bit the definition of SET_FEATURE and GET_STATUS requests to add USB3-specific details. This patch implements both changes to the Composite Gadget Framework.
