Implement power button behavior.
Implement the state machine for PWRBTN# input and output to PCH. The state
begins while power button is pressed and stops while it is released or 8 secs
pass. The state machine is maintained inside the infinite loop of gpio_task().
Remember to #define EVT after the board comes back.
Also, the power-up sequence is not completed yet. Remember to come back when
it is done. Search TODO in code.
