[PATCH v7 2/2] ASoC: dt-bindings: realtek,rt5575: add bindings for ALC5575

[Oder Chiou <oder_chiou@realtek.com>]

Realtek ALC5575 is a highly advanced DSP and microphone CODEC that has
been designed for AI audio technology. Its impressive features include
an advanced HiFi-5 DSP core, a Neural Network Processing Unit (NPU)
owned by Realtek, and embedded 4MB memory, which enables it to operate
highly advanced AI audio algorithms. The ALC5575 supports 4xA-mic input
and 8xD-mic input, as well as a rich set of interfaces such as I2S, I2C,
SPI, and UART.
