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.
