For the AF configuration, if the rightmost stripe is used, the AF scene will be at the incorrect location of the sensor. The AF coordinate may be set to the right part of the sensor. This configuration would lead to x_start being greater than the down_scaled_stripes offset and the leftmost stripe would be disabled and only the rightmost stripe is used to control the AF coordinate. If the x_start doesn't perform any adjustments, the AF coordinate will be at the wrong place of the sensor since down_scaled_stripes offset would be the new zero of the coordinate system. In this patch, if only the rightmost stripe is used, x_start should minus down_scaled_stripes offset to maintain its correctness of AF scene coordinate.
