Add support for the sink pad of scaler subdevice to respond VIDIOC_G_SELECTION and VIDIOC_S_SELECTION ioctls with the following targets: V4L2_SEL_TGT_COMPOSE_BOUNDS and V4L2_SEL_TGT_CROP. * Add new const struct crop_rect_default to initialize subdev scaler properly. * Make changes in sink pad format reflect to the crop rectangle. E.g. changing the frame format to a smaller size one can make the former crop rectangle selects a non existing frame area. To solve this situation the crop rectangle is clamped to the frame boundaries. * Clamp crop rectangle respecting the sink bounds during set_selection ioctl.
