dts: mimxrt685_evk/mimxrt685s/hifi4: Enable devs for audio
Browse files Browse the repository at this point in the history
Instantiate, configure and enable Flexcomm zephyrproject-rtos#1, Flexcomm zephyrproject-rtos#3, DMA, I3C for
audio capture and playback on mimxrt685_evk's HiFi 4 DSP domain. Add
pinmux definitions for those.
