drm/amd/display: Only add stream to freesync when modeset required

Browse Source 
This is a follow-up patch to:

Leo (Sunpeng) Li    Cleanup code that enables freesync

We should only add a stream to freesync if a modeset was requested, so
we don't fill the core freesync map with pointless streams.
