Thierry Reding e75d04771a drm/tegra: dc: Don't clean up unused display controller ...

Display controllers that don't own any windows and which therefore
aren't currently being assigned a primary plane are not registered
as a CRTC with the DRM framework. They request neither a syncpoint
nor an interrupt because they don't use them, so avoid cleaning up
those resources.
