[PATCH v4 5/6] arm64: dts: imx8mp: Add fsl,dsp-ctrl property for dsp

Audio block control contains a set of registers and some of them used for
DSP configuration.

Drivers (rproc, SOF) are using fsl,dsp-ctrl property in order to control
the DSP, particularly for Run/Stall bit.

Note that audio block control doesn't offer the functionality to reset
thte DSP. Reset is done via DAP interface.
