ASoC: msm: refactor machine driver for msmfalcon

Browse source 
Combine the common code of both external and internal
codec machine drivers. Provide config support for
independent compilation of internal and external
codecs.

micbias type, internal or external.

switch type on target typically the switch type will be normally open or
normally close, value for this property 0 for normally close and 1 for
normally open.
- qcom,msm-mbhc-gnd-swh: This property is used to distinguish headset GND
switch type on target typically the switch type will be normally open or
normally close, value for this property 0 for normally close and 1 for
normally open.

cpu dai names should match to that of the phandle order given.
- 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".
- qcom,wsa-max-devs : Maximum number of WSA881x devices present in the target
