[PATCH 32/40] drm/amd/display/amdgpu_dm/amdgpu_dm: Mark 'link_bandwidth_kbps' as __maybe_unused

'link_bandwidth_kbps' is always obtained, but only used if
CONFIG_DRM_AMD_DC_DCN is defined.

Fixes the following W=1 kernel build warning(s):

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c: In function ‘create_stream_for_sink’:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5080:11: warning: variable ‘link_bandwidth_kbps’ set but not used [-Wunused-but-set-variable]
