[media] Afatech AF9035 DVB USB driver 



AF9035 is integrated DVB USB interface and DVB-T demodulator.
Integrated demodulator is AF9033 and its driver is attached
runtime as a own module.

Driver currently supports only one device,
TerraTec Cinergy T Stick [0ccd:0093].

TerraTec Cinergy T Stick is based of Afatech AF9035 +
Infineon TUA 9001 silicon tuner.
