ASoC: msm: Add mdm9630 machine driver 



Machine driver holds target specific information for
mdm9630. DAI links and sound card for mdm9630
are registered in machine driver. Machine driver handles
clocks and gpios for MI2S interface.

* MDM9630 ASoC Machine driver



Required properties:

- compatible : "qcom,mdm9630-audio-taiko"

- qcom,model : The user-visible name of this sound card.

- qcom,audio-routing : A list of the connections between audio components.

  Each entry is a pair of strings, the first being the connection's sink,

  the second being the connection's source.

- qcom,taiko-mclk-clk-freq : Master clock value given to codec. Some WCD9XXX

  codec can run at different mclk values. Mclk value can be 9.6MHz or 12.288MHz.

  This element represents the value for MCLK provided to codec.

- qcom,prim-i2s-gpio-ws : Specifies gpio assigned for primary WS I2S pin.

- qcom,prim-i2s-gpio-din : Specifies gpio assigned for primary DIN I2S pin.

- qcom,prim-i2s-gpio-dout : Specifies gpio assigned for primary DOUT I2S pin.

- qcom,prim-i2s-gpio-sclk : Specifies gpio assigned for primary SCLK I2S pin.

- qcom,prim-i2s-gpio-mclk : Specifies gpio assigned for MCLK I2S pin.

	sound {

                compatible = "qcom,mdm9630-audio-taiko";
