PATCH 1/2 dt-bindings: gpio: Add Tegra238 support

Extend the existing Tegra186 GPIO controller device tree bindings with support for the GPIO controllers found on Tegra238. Tegra238 has two GPIO controllers: the main controller and always-on (AON) controller. The number of pins is slightly different, but the programming model remains the same.

Add a new header, include/dt-bindings/gpio/nvidia,tegra238-gpio.h, that defines port IDs as well as the TEGRA238_MAIN_GPIO() helper, both of which are used in conjunction to create a unique specifier for each pin.
