Broadcom DSL/PON BCM63xx Audio I2S controller

Required properties:
- compatible:     Should be "brcm,bcm63xx-i2s".
- #address-cells: 32bit valued, 1 cell.
- #size-cells:    32bit valued, 0 cell.
- reg:            Should contain audio registers location and length
- interrupts:     Should contain the interrupt for the controller.
- clocks:         Must contain an entry for each entry in clock-names.
                  Please refer to clock-bindings.txt.
- clock-names:    One of each entry matching the clocks phandles list:
                  - "i2sclk" (generated clock) Required.
                  - "i2sosc" (fixed 200MHz clock) Required.

(1) : The generated clock is required only when any of TX and RX
      works on Master Mode.
(2) : The fixed 200MHz clock is from internal chip and always on

Example:

		i2s: bcm63xx-i2s {
			#address-cells = <1>;
			#size-cells = <0>;
			compatible = "brcm,bcm63xx-i2s";
			reg = <0xFF802080 0xFF>;
			interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;
			clocks = <&i2sclk>, <&osc>;
			clock-names = "i2sclk","i2sosc";
		};
