[PATCH 3/3] ASoC: Intel: avs: Add rt5640 machine board

[Cezary Rojewski <cezary.rojewski@intel.com>]

To support connection between Intel AudioDSP and Realek 5640 codec
implement avs_rt5640 machine board driver. The codec chip is located on
I2C bus and the streaming occurs over I2S interface. A number of such
devices can be connected simultaneously to the platform. Majority of the
board's behavior is inherited from existing representatives such as
avs_rt274.
