f_sdp: Change bInterval of interrupt endpoint to 3
Since the USB HID limits the maximum bandwidth(3072) for interrupt endpoint transfers, when the bInterval set to 1, we can only support 3 boards to run sdp at the same time. In order to support more boards, change the bInterval of interrupt endpoint to 3, which will not affect the transmission speed.
