ITE: soc/power: add power management

Add the power state of deep doze. When system enters deep doze, the
clock of CPU and EC can be stopped to reduce power consumption. And
enable the UART Rx WUI before entering deep doze to wake up EC and
CPU.

Tested on it8xxx2_evb board. It will reduce 5.25mA when system enters
deep doze mode.
