[PATCH 02/16] drm/amd/display: Get visual confirm color for stream

[Aurabindo Pillai]

From: Leo Zeng <Leo.Zeng at amd.com>

[WHY]
We want to output visual confirm color based on stream.

[HOW]
If visual confirm is for DMUB, use DMUB to get color.
Otherwise, find plane with highest layer index, output visual confirm color
of pipe that contains plane with highest index.
