arm64: dts: imx8mp: Add dsp node
i.MX8 MPlus SoC integrates Cadence HIFI4 DSP. This core runs either a
custom firmware or the open source SOF firmware [1]
DSP device is handled by SOF OF driver found in
sound/soc/sof/sof-of-dev.c
Notice that the DSP node makes use of:
- dsp_reserved, a reserved memory region for various Audio
resources (e.g firmware loading, audio buffers, etc).
- Messaging Unit (mu2) for passing notifications betweem ARM
core and DSP.
