usb: dwc3: gadget: let us set lower max_speed
In some SoCs, dwc3 is implemented as a USB2.0 only
core, meaning that it can't ever achieve SuperSpeed.
Currect driver always sets gadget.max_speed to
USB_SPEED_SUPER unconditionally. This can causes
issues to some Host stacks where the host will issue
a GetBOS() request and we will reply with a BOS
containing Superspeed Capability Descriptor.
At least Windows seems to be upset by this fact and
prints a warning that we should connect $this device
to another port.
