ASoC: remove zte zx drivers

ZTE TDM DAI driver

Required properties:

- compatible : should be one of the following.

       * zte,zx296718-tdm

- reg : physical base address of the controller and length of memory mapped

    region.

- clocks : Pairs of phandle and specifier referencing the controller's clocks.

- clock-names: "wclk" for the wclk.

               "pclk" for the pclk.

-#clock-cells: should be 1.

- zte,tdm-dma-sysctrl : Reference to the sysctrl controller controlling

    the dma. includes:

	phandle of sysctrl.

	register offset in sysctrl for control dma.

	mask of the register that be written to sysctrl.

Example:

	tdm: tdm@1487000 {

		compatible = "zte,zx296718-tdm";

		reg = <0x01487000 0x1000>;

		clocks = <&audiocrm AUDIO_TDM_WCLK>, <&audiocrm AUDIO_TDM_PCLK>;

		clock-names = "wclk", "pclk";

		#clock-cells = <1>;

		pinctrl-names = "default";

		pinctrl-0 = <&tdm_global_pin>;

		zte,tdm-dma-sysctrl = <&sysctrl 0x10c 4>;

	};

ZTE ZX AUD96P22 Audio Codec

Required properties:

 - compatible: Must be "zte,zx-aud96p22"

 - #sound-dai-cells: Should be 0

 - reg: I2C bus slave address of AUD96P22

Example:

	i2c0: i2c@1486000 {

		compatible = "zte,zx296718-i2c";

		reg = <0x01486000 0x1000>;

		interrupts = <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>;

		#address-cells = <1>;

		#size-cells = <0>;

		clock-frequency = <1600000>;

		aud96p22: codec@22 {

			compatible = "zte,zx-aud96p22";

			#sound-dai-cells = <0>;

			reg = <0x22>;

		};

	};

ZTE ZX296702 I2S controller

Required properties:

 - compatible : Must be one of:

	"zte,zx296718-i2s", "zte,zx296702-i2s"

	"zte,zx296702-i2s"

 - reg : Must contain I2S core's registers location and length

 - clocks : Pairs of phandle and specifier referencing the controller's clocks.

 - clock-names: "wclk" for the wclk, "pclk" for the pclk to the I2S interface.

 - dmas: Pairs of phandle and specifier for the DMA channel that is used by

   the core. The core expects two dma channels for transmit.

 - dma-names : Must be "tx" and "rx"
