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.
