drivers/periph_usbdev: define USBDEV_SET_ADDR_AFTER_STATUS

Browse Source 
The address in the USB device can be set either directly after the SETUP stage on receipt of the `SET ADDRESS Request` or after the associated status stage. When the USB device address has to be set depends on the hardware. If `USBDEV_SET_ADDR_AFTER_STATUS` has the value 1 (default), the address is only set in the USB device after the status stage. Overwrite it with 0 in `periph_cpu.h` to set the address already directly after the SETUP stage.
