Randall Spangler 30a33e6b04 Drop DPWROK when system is off for more than 10 sec ...

This saves ~70mw of power.

To make this work, I also had to stretch the power button signal to
give the system a chance to come back up when the user taps the power
button.

TEST=manual

For each of the following tests, wait ~15 sec after the system is
powered off to give it a chance to drop DPWROK.

1) tap power button -> system turns on
2) hold power button 1 sec -> system turns on
3) open lid -> system turns on
4) silego reset (power+refresh, or power+esc on proto1) -> system stays off
5) silego recovery (power+esc+refresh) -> system turns on
6) hold down power button and type 'reboot' on EC console -> system turns on
7) type 'powerbtn' on EC console -> system turns on
