drm/tegra: Update to Linux v6.12

Browse Source 
Update Tegra DRM to align with Linux v6.12. The output.c driver was
updated to use the 'drm_edid_connector_add_modes()' function that was
first added in Linux v6.3. Use conftest to detect the presence of the
drm_edid_connector_add_modes() function and make the necessary changes
to the driver.
