USB: serial: cp210x: add ID for Ingenico 3070

Here is how this device appears in kernel log:

	usb 3-1: new full-speed USB device number 18 using xhci_hcd
	usb 3-1: New USB device found, idVendor=0b00, idProduct=3070
	usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
	usb 3-1: Product: Ingenico 3070
	usb 3-1: Manufacturer: Silicon Labs
	usb 3-1: SerialNumber: 0001

Apparently this is a POS terminal with embedded USB-to-Serial converter.
