  Add GTE nodes for the tegra234. Also modify AON GTE nodes for the
tegra194 to remove nvidia,slice property and add nvidia,gpio-controller
property to specify AON GPIO controller node so that GTE driver can
do namespace conversion between GPIO lines provided by the gpiolib
framework and hardware timestamping engine subsystem.
