Subject: [PATCH] amd/display/dc: Fix COLOR_ENCODING and COLOR_RANGE doing
nothing for DCN20+

For DCN20 and above, the code that actually hooks up the provided input_color_space got lost at some point.

Fixes COLOR_ENCODING and COLOR_RANGE doing nothing on DCN20+. Tested using Steam Remote Play Together + gamescope.

Update other DCNs the same wasy DCN1.x was updates in
commit a1e07ba89d49 ("drm/amd/display: Use plane->color_space for dpp if specified")

Fixes a1e07ba89d49 ("drm/amd/display: Use plane->color_space for dpp if specified")
