ASoC: codecs: Add Awinic AW88395 audio amplifier 

Merge series from wangweidong.a@awinic.com:

The Awinic AW88395 is an I2S/TDM input, high efficiency
digital Smart K audio amplifier with an integrated 10.25V
smart boost converter.

Add a DT schema for describing Awinic AW88395 audio amplifiers. They are
controlled using I2C
