    hw: Only compile the usb-dwc2 controller if it is really needed
    
    The USB_DWC2 switch is currently "default y", so it is included in all
    qemu-system-* builds, even if it is not needed. Even worse, it does a
    "select USB", so USB devices are now showing up as available on targets
    that do not support USB at all. This sysbus device should only be
    included by the boards that need it, i.e. by the Raspi machines.
