Shawn Guo 9e42b263e8 drm: zte: move CSC register definitions into a common header
The CSC (Color Space Conversion) block in VOU is used by not only
Graphic Layer (plane) but also channel (CRTC) module.  Let's move
its register definitions into a common header, so that CRTC driver can
include it when needed.
