The USB_DEVICE() list contain some of the product names, but
some are missing, and others are different than the message
printed during device detection.
Update the comments in order to match what the driver prints.
That makes easier to discover what model matches what physical
device.

Instead of using USB_DEVICE() macro directly, use the
DVB_USB_DEVICE() one, as other dvb-usb-v2 devices.
The usage of the new macro makes cleaner and easier to
parse the supported device names in a way that it would
be easily parseable to generate cardlists.
