Subject: [PATCH 5/5] drm/amd/display: Remove the unused function copy_stream_update_to_stream()

The function copy_stream_update_to_stream() is defined in the notif.c
file, but not called elsewhere, so delete this unused function.

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:2852:6: warning: no previous prototype for ‘dc_reset_state’.
