ARM: dt: tegra: Add Tegra APB DMA device tree binding 



Document binding, and add the node to tegra*.dtsi.

The driver isn't actually instantiated from this node yet, but the I2S
binding will rely on being able to refer to the APB DMA node using a
phandle.

* NVIDIA Tegra APB DMA controller



Required properties:

- compatible: Should be "nvidia,<chip>-apbdma"

- reg: Should contain DMA registers location and length. This shuld include

  all of the per-channel registers.

- interrupts: Should contain all of the per-channel DMA interrupts.



Examples:



apbdma: dma@6000a000 {

	compatible = "nvidia,tegra20-apbdma";

	reg = <0x6000a000 0x1200>;

	interrupts = < 0 136 0x04
