From: "Nícolas F. R. A. Prado" <redacted> As a preparatory step for supporting CRTC (post-blend) color pipelines in VKMS, rename pre_blend_color_transform() to color_transform() and make it take the first colorop instead of a plane state, so it can be shared by both plane (pre-blend) and CRTC (post-blend) color pipeline code paths.
