dumbfb: Fix pitch for tri-planar formats
The BO pitches are unconditionally set to the frame buffer pitch, for all planes. This is correct for semiplanar YUV formats, as they subsample chroma horizontally by two but combined U and V in a single plane, cancelling each other. For fully planar YUV formats, however, the horizontal subsampling need to be taken into account to compute the pitch. Fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
