Jean Delvare 0a5f1f211f [media] i2c: Stop using I2C_CLASS_TV_ANALOG 
Detection class I2C_CLASS_TV_ANALOG is set by a few adapters but no
I2C device driver is setting it anymore, which means it can be
dropped. I2C devices on analog TV adapters are instantiated
explicitly these days, which is much better.
