[media] omap3isp: preview: Remove horizontal averager support
The horizontal averager isn't used and will get in the way when implementing cropping support on the input pad. Remove it, it can be added back later if needed. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
