V4L/DVB (5121): Proper vendor/device ID for the CinergyT2 input device

I noticed that udev does not create a symlink for the CinergyT2 remote input
device in /dev/input/by-id, which is required if I want to have a
unique device name for lircd.
The attached patch tries to achive this. However, udev still omits the
input device for /dev/input/by-id symlinks. I think something is still
not reported correctly.
