drm/amd/display: Preserve original aspect ratio in create stream
[Why] The original picture aspect ratio in mode struct may have chance be overwritten with wrong aspect ratio data in create_stream_for_sink(). It will create a different VIC output and cause HDMI compliance test failed. [How] Preserve the original picture aspect ratio data during create the stream.
