* ov7670: fix ov7670_frame_control()
Last value of array (VREF) was overwritten by end marker
* OV7670: Adapt QQVGA VSTART value to remove bar on top
Remove empty bar at the top of the frame. This is more visible on
OV7675, but also present on OV7670
When I use OV7725 and OV7670, I can't get the image. This pr modifies the VSYNC register of OV7725 7670, and the image can be obtained normally, and the white balance is adjusted to make the obtained image normal.
