V4L/DVB: The first two parameters of soc_camera_limit_side() are usually pointers to struct v4l2_rect elements. They are signed, so adjust the prototype accordingly

This will remove the following sparse warning (see "make C=1"):

 * incorrect type in argument 1 (different signedness)
       expected unsigned int *start
       got signed int *<noident>

as well as a couple more signedness mismatches.
