hverkuil/go7007: media: i2c : tw2804: Revert ADC Control Reverting patch commit 3d321ebba68f1fc50a9461373e8da0887e39fbbc Case: In AdLink MPG24 there is bt878 exists (it captures one frame of all video inputs), Video Signal for it one transmits through tw2804 chip, so we can`t control ADC (shut on/off) on tw2804 ,as some another can use bttv capture way.
