[PATCH 2/4] drm: zte: move CSC register definitions into a common header

[Shawn Guo]

From: Shawn Guo <shawn.guo at linaro.org>

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.
