[PATCH 13/21] drm/amd/display: Update scaler recout data for visual confirm

[Rodrigo Siqueira]

From: "Leo (Hanghong) Ma" <hanghong.ma at amd.com>

[Why]
Our QA found visual confirm color is not as expected for Auto
Color Management feature test after enable it.

[How]
Calculate scaler recout data when visual confirm enabled to update
the visual confirm bar on the display.
