Protect remove_hpo_dp_link_enc_from_ctx() and release_hpo_dp_link_enc()
with CONFIG_DRM_AMD_DC_DCN as the functions are only called from code
that is protected by CONFIG_DRM_AMD_DC_DCN. Fixes build fail with
-Werror=unused-function.
Fixes: 9b0e0d433f74 ("drm/amd/display: Add dependant changes for DCN32/321")
