Handle clocks and mailbox channels at runtime suspend/resume in order to save power. DSP runtime PM uses a timeout of 2s. If device is idle for 2s system will enter runtime suspend. Because SOF state machine assumes that even if the DSP wasn't previously active at a System resume, will re-load the firmware we need to make sure that all needed resources are active. Kernel core will take care of enabling the PD, we need to make sure that we request the MU channels.
