mt9t031: improve rectangle placement in invalid S_CROP

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

1. soc-camera always requests a valid rectangle, when calling .s_fmt(), no need
to check and adjust
2. in .s_crop(), if the rectangle exceeds sensor limits, push it to the
respective border instead of centering
3. take into account left and top borders when checking
