ARM: tegra: define DT bindings for and instantiate RTC
The Tegra RTC maintains seconds and milliseconds counters, and five alarm registers. The alarms and other interrupts may wake the system from low-power state. Define a DT binding for this HW module, and add the module into the Tegra device tree files. Signed-off-by: Stephen Warren <swarren@nvidia.com>

+NVIDIA Tegra20 real-time clock
+
+The Tegra RTC maintains seconds and milliseconds counters, and five alarm
+registers. The alarms and other interrupts may wake the system from low-power
+state.
+
+Required properties:
+
+- compatible : should be "nvidia,tegra20-rtc".
+- reg : Specifies base physical address and size of the registers.
+- interrupts : A single interrupt specifier.
+
+Example:
+
+timer {
+ compatible = "nvidia,tegra20-rtc";
+ reg = <0x7000e000 0x100>;
+ interrupts = <0 2 0x04>;
+};
