Stephen Warren 2f2b7fb202 ARM: tegra: define DT bindings for and instantiate timer
The Tegra timer provides a number of 29-bit timer channels, a single
32-bit free running counter, and in the Tegra30 variant, 5 watchdog modules.
The first two channels may also trigger a legacy watchdog reset.

Define a DT binding for this HW module, and add the module into the Tegra
device tree files.

NVIDIA Tegra20 timer
The Tegra20 timer provides four 29-bit timer channels and a single 32-bit free
running counter. The first two channels may also trigger a watchdog reset.
Required properties:
- compatible : should be "nvidia,tegra20-timer".
- reg : Specifies base physical address and size of the registers.
- interrupts : A list of 4 interrupts; one per timer channel.
Example:
timer {
compatible = "nvidia,tegra20-timer";
reg = <0x60005000 0x60>;
interrupts = <0 0 0x04
0 1 0x04
0 41 0x04
0 42 0x04>;
};
