sys/auto_init/usb: add a check for the number EPs

Browse Source 
Since `auto_init_usb` provides a static auto configuration for a single USBUS stack instance using a single USB device, a static assert can be used here to check whether the number of EPs required by the configuration does not exceed the number of EPs provided by the USB device.
