drm/amd/display: Cover dm_validate_stream_and_context

Browse source

Add dm_test_validate_stream_dc_ok_no_pipe which builds a minimal fake
dc so stream and plane validation both pass, then lets
dc_state_add_stream() bail out early via timing_generator_count == 0 to
avoid deep pipe allocation, raising coverage from 24% to 90%.
