ASoC: cs35l56: Add driver for Cirrus Logic CS35L56
The CS35L56 combines a high-performance mono audio amplifier, Class-H tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost converter supporting Class-H tracking. Supported control interfaces are I2C, SPI or SoundWire. Supported audio interfaces are I2S/TDM or SoundWire. Most chip functionality is controlled by on-board ROM firmware that is always running. The driver must apply patch/tune to the firmware before using the CS35L56.
