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.

By default the scanning code would pull-low all column pins and listen to
any key press interrupt on input pins. This can save power compared to the
repeatly polling.
Once a key is pressed, the scanning code enters the busy loop and pull-low
column pins one by one. Then generate the scan code to host.
The code keeps polling after 1 second after no key is pressed. Then goes
back to interrupt mode.
BUG=none
TEST=Manual tested on S*y machine.
