[media] media: omap3isp: hist: Move histogram DMA to DMA engine

Browse source 
Replace the custom OMAP DMA API usage by DMA engine. Feature-wise the
driver has lost the ability to get notified of DMA transfers failure
through the completion handler, as the DMA engine API doesn't expose
that status information.
