libcamera: Use utils::abs_diff()
Use the new utils::abs_diff() function where appropriate to replace manual implementations. While at it fix a header ordering issue in src/libcamera/pipeline/raspberrypi/raspberrypi.cpp. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>
