Subject: [RFC PATCH v2 05/13] arm/dt: Tegra: Add nvidia,gpios property to GPIO controller

Add board-specific gpio node for Harmony and Seaboard. This lists the
GPIOs used by the board. Note that not all GPIOs that exist on the board
are listed; only those used by devices currently supported by device
tree.
