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. Changes in v2: 1. Remove the setting of the first stripe.
