RT5651 audio CODEC

This device supports I2C only.

Required properties:

- compatible : "realtek,rt5651".

- reg : The I2C address of the device.

Optional properties:

- realtek,in2-differential
  Boolean. Indicate MIC2 input are differential, rather than single-ended.

- realtek,dmic-en
  Boolean. true if dmic is used.

Pins on the device (for linking into audio routes) for RT5651:

  * DMIC L1
  * DMIC R1
  * IN1P
  * IN2P
  * IN2N
  * IN3P
