watchdog: Add tegra watchdog
Add a driver for the hardware watchdogs in NVIDIA Tegra SoCs (Tegra30 and later). This driver will configure one watchdog timer that will reset the system in the case of a watchdog timeout. This driver binds to the nvidia,tegra30-timer device node and gets its register base from there.
