This patch converts Rockchip rk3328 audio codec binding to DT schema.
And adds description about "mclk" clock and fixes some errors in
original example.

-* Rockchip Rk3328 internal codec
-
-Required properties:
-
-- compatible: "rockchip,rk3328-codec"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- rockchip,grf: the phandle of the syscon node for GRF register.
-- clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
-- clock-names: should be "pclk".
-- spk-depop-time-ms: speak depop time msec.
-
-Optional properties:
-
-- mute-gpios: GPIO specifier for external line driver control (typically the
- dedicated GPIO_MUTE pin)
-
-Example for rk3328 internal codec:
-
-codec: codec@ff410000 {
- compatible = "rockchip,rk3328-codec";
- reg = <0x0 0xff410000 0x0 0x1000>;
- rockchip,grf = <&grf>;
- clocks = <&cru PCLK_ACODEC>;
- clock-names = "pclk";
- mute-gpios = <&grf_gpio 0 GPIO_ACTIVE_LOW>;
- spk-depop-time-ms = 100;
-};
