From: Andrey Grodzovsky <Andrey.Grodzovsky at amd.com>
Summury of changes:
1: Both in check and commit Connector properties were handled as
part of for_each(crtc) loop while they shoud have been handled
in a dedicated for_each(connector)
loop since they are connector properties. Moved.
2: Removed hacky plane add in amdgpu_dm_connector_atomic_set_property
to force iteration on plane forconnector property. This was
causing double call to commit_surface_for_stream both in crtc loop
and plane loop.
3: Remove middleman DC interface and call dc_commit_surfaces_to_stream
directly to increase code clarity.
Remove it from atomic_commit.
