drm/tegra: Fix aperture support for Linux v6.13

Browse Source 
In Linux v6.13, commit 689274a56c0c ("drm: Remove DRM aperture helpers")
removed the DRM aperture helper functions and drivers should simply use
the existing video helpers. Update the Tegra DRM driver to use
aperture_remove_all_conflicting_devices() if available to align with
upstream.
