drm/rockchip: Disable blending for win0
Blending win0 with the background color doesn't seem to work correctly. We only get the background color, no matter the contents of the win0 framebuffer. However, blending pre-multiplied color with the default opaque black default background color is a no-op, so we can just disable blending to get the correct result. Signed-off-by:Kristian H.
