Steve Longerbeam fee7782908 gpu: ipu-v3: image-convert: Enable double write reduction 
For the write channels with 4:2:0 subsampled YUV formats, avoid chroma
overdraw by only writing chroma for even lines (skip odd chroma rows).
This reduces necessary write memory bandwidth by at least 25% (more
with rotation enabled).
