dt-bindings: i2c: tegra: Document Tegra210 VI I2C 



The Tegra210 features an instance of the Tegra I2C controller that is
part of the host1x domain and typically used for camera use-cases. It
uses pretty much the same programming model but the registers are laid
out differently.

  nvidia,tegra210-i2c-vi: Tegra210 has one I2C controller that is part of the

	host1x domain and typically used for camera use-cases. This VI I2C

	controller is mostly compatible with the programming model of the

	regular I2C controllers with a few exceptions. The I2C registers start

	at an offset of 0xc00 (instead of 0), registers are 16 bytes apart

	(rather than 4) and the controller does not support slave mode.

- reg: Should contain I2C controller registers physical address and length.

- interrupts: Should contain I2C controller interrupts.

- address-cells: Address cells for I2C device address.
