Subject: [PATCH] drm/amdgpu/display: fix logic regression in dce110 apply_single_controller_ctx_to_hw

Commit 5de27e1d6755 ("drm/amd/display: Add DP 2.0 SST DC Support") added a new check for DP 2.0 with a CONFIG_DRM_AMD_DC_DCN check that removed a bunch of logic if CONFIG_DRM_AMD_DC_DCN was not set, restore that logic.
