The ov772x driver provides three V4L2 controls and the current value of each control is saved as a variable in the private data structure. We don't need to keep track of the current value by ourself, if we use v4l2_ctrl returned from v4l2_ctrl_new_std() instead. This is a preparatory change to avoid accessing registers under power saving mode. This simplifies s_ctrl() by making it just return without saving the current control value in private area when it is called under power saving mode.
