Jerry: modify gpio config, hibernate
Added hibernate wakeup pin(EC_WAKE) that covers both AC_PRESENT and LID_OPEN. It pulses a
rising edge when either of them have a rising edge.
The power button was also inverted to handle hibernation better, now it's low
except when pressed it temporarly goes high.
BRANCH=None
BUG=chrome-os-partner:33269 chrome-os-partner:32782
TEST=make BOARD=jerry
Try hibernating, all wakeup sources should work, it shouldn't stay hibernated.
All signals(AC, lid, power button) should work equally well as in pinky.
