media: ov772x: use v4l2_ctrl to get current control value
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.
