Fixes gcc '-Wunused-function' warning: ‘update_dsc_caps’ and ‘apply_dsc_policy_for_stream’ are only used if 'CONFIG_DRM_AMD_DC_DCN' is defined, however, it's defined even if 'CONFIG_DRM_AMD_DC_DCN' is not defined. Thus gcc will report following warning if 'CONFIG_DRM_AMD_DC_DCN' is not defined: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5572:13: warning: ‘apply_dsc_policy_for_stream’ defined but not used [-Wunused-function] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5556:13: warning: ‘update_dsc_caps’ defined but not used [-Wunused-function] Thus move the definition of ‘update_dsc_caps’ and ‘apply_dsc_policy_for_stream’ inside define macro to fix it.
