Subject: [media] omap3isp: preview: Fix the crop margins

commit 8b57b9669aa884ac75b8d09c251d6b1755533c15 upstream.

Commit 3fdfedaaa "[media] omap3isp: preview: Lower the crop margins"
accidentally changed the previewer's cropping, causing the previewer
to miss four pixels on each line, thus corrupting the final image.
Restored the removed setting.
