[PATCH xf86-video-amdgpu 13/13] Refactor pushing color management properties into a function

[sunpeng.li@xxxxxxx (sunpeng.li at amd.com)]

From: "Leo (Sunpeng) Li" <sunpeng.li@xxxxxxx>

Pushing all color properties to kernel DRM is done in a few places.
Reduce repetition by refactoring into a function.
