ASoC: dt-bindings: tegra30-i2s: convert to dt schema

Convert NVIDIA Tegra30 I2S binding to DT schema and
add "clock-names" property used by multiple tegra i2s blocks
in arch/arm64/boot/dts/nvidia/tegra132.dtsi. This is not a
required property by the binding.

-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";
-};
