[media] v4l/dvb: add support for AVerMedia AVerTV Red HD+ (A850T)

The AVerTV Red HD+ (A850T) is basically the same as the existing
AVerTV Volar Black HD (A850), but is specific to the french market.
The A850T identifies itself as a A850, but has its own PID. It even
suffers from the same EEPROM deficiencies.

This is based off a collection of information gathered from the
french support forums for Ubuntu, which I tried to properly format
into this patch:
