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.
