NVIDIA Tegra30 I2S controller

Required properties:
- compatible : For Tegra30, must contain "nvidia,tegra30-i2s".  For Tegra124,
  must contain "nvidia,tegra124-i2s".  Otherwise, must contain
  "nvidia,<chip>-i2s" plus at least one of the above, where <chip> is
  tegra114 or tegra132.
- reg : Should contain I2S registers location and length
- clocks : Must contain one entry, for the module clock.
  See ../clocks/clock-bindings.txt for details.
- resets : Must contain an entry for each entry in reset-names.
  See ../reset/reset.txt for details.
- reset-names : Must include the following entries:
  - i2s
- nvidia,ahub-cif-ids : The list of AHUB CIF IDs for this port, rx (playback)
  first, tx (capture) second. See nvidia,tegra30-ahub.txt for values.

Example:

i2s@70080300 {
	compatible = "nvidia,tegra30-i2s";
	reg = <0x70080300 0x100>;
	nvidia,ahub-cif-ids = <4 4>;
	clocks = <&tegra_car 11>;
	resets = <&tegra_car 11>;
	reset-names = "i2s";
};
