ASoC: SSM2602: Add SSM2604 support
The SSM2604 is basically a lightweight variant of the SSM2602 with a compatible register layout. Thus we can easily support both devices by the same driver, by providing a slightly set of controls, widgets and routes. Compared to the SSM2602 the SSM2604 has no microphone input and no headphone output.
