ES8311 audio codec

A driver for the ES8311 audio codec by Everest Semiconductor, wired as a dual in/out AUDIO_CODEC_TYPE device (speaker output + microphone input on the same chip). The I2C bus is the device's parent; the I2S controller carrying audio data is referenced via a devicetree phandle.

Wraps Espressif's esp_codec_dev ES8311 implementation.
