dsp_clock_disable_all - Disable all active clocks Driver's device context structure

This function disables all the peripheral clocks that were enabled by DSP. It is meant to be called only when DSP is entering hibernation or when DSP is in error state.

dsp_clock_enable_all - Enable clocks used by the DSP Driver's device context strucure

This function enables all the peripheral clocks that were requested by DSP.
