gpu: ipu-v3: Add support for double read/write reduction
Allow to skip writing odd chroma rows by setting the RDRW bit for 4:2:0 chroma subsampled formats for any IDMAC write channel. This also allows to skip reading odd rows for the VDIC read channel. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
