ASoC: Add initial ZL38060 driver
The ZL38060 is a "Connected Home Audio Processor" from Microsemi, which consists of a Digital Signal Processor (DSP), several Digital Audio Interfaces (DAIs), analog outputs, and a block of 14 GPIOs. This driver supports only a tiny subset of the chip's functionality and possible configurations: - bypass mode (whole dsp block is bypassed) - chip's I2S DAI routed directly to/from DACs and microphone - chip's internal clock is driven by a 12 MHz external crystal - chip's DAI connected to CPU is I2S, and bit + frame clock master - chip must be strapped for "host boot": in this mode, firmware will be provided by this driver.
