[PATCH V4 3/7] ASoC: codecs: Modify the transmission method of parameters and property node

[wangweidong.a@awinic.com]

From: Weidong Wang <wangweidong.a@awinic.com>

Remove the fade-enable property because other properties
already implement this functionality.
Modify the transmission method of parameters.
Rename "sound-channel" to "awinic,audio-channel"
