ASoC: mdm9640: Add machine driver for MDM 9640 



Machine driver holds target specific information for
mdm9640. DAI links and sound card for 9640 are registered
in machine driver. Machine driver handles clocks for
MI2S interface.

* MDM9640 ASoC Machine driver



Required properties:

- compatible : "qcom,mdm9640-audio-tomtom" for tomtom codec

- 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,codec-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.

- asoc-platform: This is phandle list containing the references to platform device

		 nodes that are used as part of the sound card dai-links.

- asoc-platform-names: This property contains list of platform names. The order of

		       the platform names should match to that of the phandle order

		       given in "asoc-platform".

- asoc-cpu: This is phandle list containing the references to cpu dai device nodes

	    that are used as part of the sound card dai-links.

- asoc-cpu-names: This property contains list of cpu dai names. The order of the

		  cpu dai names should match to that of the phandle order given

		  in "asoc-cpu". The cpu names are in the form of "%s.%d" form,

		  where the id (%d) field represents the back-end AFE port id that

		  this CPU dai is associated with.

- asoc-codec: This is phandle list containing the references to codec dai device

	      nodes that are used as part of the sound card dai-links.

- asoc-codec-names: This property contains list of codec dai names. The order of the

		    codec dai names should match to that of the phandle order given

		    in "asoc-codec".



Optional Properties:

- qcom,mi2s-interface-mode: This property contains mi2s interface modes master/ slave.

			    Entry is a pair of strings, the first being for primary mi2s

			    and the second for secondary mi2s and so on

- qcom,auxpcm-interface-mode: This property contains auxpcm interface modes master/ slave.

			      Entry is a pair of strings, the first being for primary auxpcm

			      and the second for secondary auxpcm and so on
