Add clock gating to the device suspend/resume sequence to decrease power consumption on the Device side.
Measurements
SoC current was measured on esp32s31 dev board featuring current measurement jumper.
The measurements show, that the added clk gating saved more than 10% more power when compared to the suspended state without clk gating.
