ASoC: msm: Add machine driver for APQ8096 based automotive platform 



Add machine driver for APQ8096 based automotive platform. The machine
driver is based on msm8996.c. On top of it, add support for TDM which
is used for data transfer between APQ8096 and the automotive COODEC HW,
the changes include add TDM backend and frontend DAI links as well as
kcontrol functions to configure TDM channels.

* APQ8096 Automotive ASoC Machine driver



Required properties:

- compatible : "qcom,apq8096-asoc-snd-auto" for auto codec and

		node is "sound-auto"

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

- 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".
