[PATCH 02/19] drm/amd/display: Fix test pattern color space inconsistency for Linux

[Rodrigo Siqueira]

From: "Jerry (Fangzhi) Zuo" <Jerry.Zuo at amd.com>

[why]
When reprogram MSA with updated color space, the test color space shows
inconsistency. Linux has separate routine to set up test pattern color
space, but it fails to configure RGB.

[How]
Add RGB to test pattern.

Fixes: 282243fab ("dc: update MSA and VSC SDP on video test pattern request")
