dt-bindings: tegra: Changes for v4.18-rc1

This contains the device tree bindings updates for the memory controller
hot resets that are implemented by driver patches in a different branch.

NVIDIA Tegra30 MC(Memory Controller)



Required properties:

- compatible : "nvidia,tegra30-mc"

- reg : Should contain 4 register ranges(address and length); see the

  example below. Note that the MC registers are interleaved with the

  SMMU registers, and hence must be represented as multiple ranges.

- interrupts : Should contain MC General interrupt.



Example:

	memory-controller {

		compatible = "nvidia,tegra30-mc";

		reg = <0x7000f000 0x010

		       0x7000f03c 0x1b4

		       0x7000f200 0x028

		       0x7000f284 0x17c>;

		interrupts = <0 77 0x04>;

	};
