Add analog audio support based on the Everest Semi ES8316 codec. Note, that this currently does not support headphone plug events. The Rock 5A uses a different headphone jack with a different logic to detect a headphone plug. Unfortunately the detect GPIO is always low. Downstream uses an ADC channel instead, but that is currently not supported upstream.
