ASoC: rt1011: Add RT1011 amplifier driver

RT1011 Mono Class D Audio Amplifier

This device supports I2C only.

Required properties:

- compatible : "realtek,rt1011".

- reg : The I2C address of the device. This I2C address decide by

        two input pins (ASEL1 and ASEL2).

        -------------------------------------

        |   ASEL2   |  ASEL1   |  Address   |

        -------------------------------------

        |     0     |    0     |   0x38     |

        -------------------------------------

        |     0     |    1     |   0x39     |

        -------------------------------------

        |     1     |    0     |   0x3a     |

        -------------------------------------

        |     1     |    1     |   0x3b     |
