ASoC: max98396: add amplifier driver

This series of patches adds support for Analog Devices MAX98396
mono amplifier with IV sense. The device provides a PCM interface
for audio data and a standard I2C interface for control data
communication. This driver also supports MAX98397 which is
a variant of MAX98396 with wide input supply range.
