ASoC: dt-bindings: Add Cirrus Logic CS48L32 audio DSP
The CS48L32 is an Audio DSP with microphone inputs and SPI control interface. It has a programmable DSP and a variety of power-efficient fixed-function audio processors, with configurable digital mixing and routing. Most properties are core properties: supply regulators, gpios, clocks, interrupt parent and SPI interface. The custom properties define the configuration of the microphone inputs to match what is physically attached to them.
