drm/amd/display: Handle multiple streams sourcing same surface

Browse source

[why]
There are cases where more than 1 stream can be mapped to the same
surface. DML2.0 does not seem to handle these cases.

[how]
Make sure to account for the stream id when deriving the plane id. By
doing this, each plane id will be unique based on the stream id.
