usb: gadget: udc: renesas_usb3: add USB ID signal monitoring
This usb 3.0 peripheral controller has a register (USB_OTG_STA) to monitor the USB ID signal. So, this patch adds the ID signal monitoring to change the mode to host (A-Host) or peripheral (B-Peripheral). This patch also removes hardcoded setting as B-Peripheral mode.
