[PATCH] drm/amd/display: Remove redundant AUTO color format handling in else

[Nicolas Frattaroli <nicolas.frattaroli@collabora.com>]

The AUTO connector color format is handled in the earlier branches for
both RGB and YUV420. The repeated check in the else branch is therefore
redundant.

Remove it to make the code less confusing to read.
