To save power soc-camera powers subdevices down, when they are not in use,
if this is supported by the platform. However, the V4L standard dictates,
that video nodes shall preserve configuration between uses. This requires
runtime power management, which is implemented by this patch. It allows
subdevice drivers to specify their runtime power-management methods, by
assigning a type to the video device.

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.
