ASoC: Intel: catpt: Do not wake DSP just for volume setup
With the new control-operations in place, the controls no longer wake
the DSP just for the sake of updating volume (or mute) settings on the
firmware side. The values are cached and actual update occurs only when
streams are being opened for streaming or are already running. In those
cases the DSP must already be woken up and we avoid unnecessary power
consumption.
