[PATCH 10/12] drm/amd/display: Add additional config guards for DCN

[Qingqing Zhuo]

From: Aurabindo Pillai <aurabindo.pillai at amd.com>

[Why&How]

Fix build error by protecting code with config guard
to enable building amdgpu without CONFIG_DRM_AMD_DC_DCN
enabled. This option is disabled by default for allmodconfig.
