pit: AC detect signal is a simple GPIO now
Frank's reworks turn AC_PWRBTN_L from a signal which co-mingled
AC-detect and pwower button press to a straight AC detect signal.
Switch from the hacky snow version of extpower to the simple gpio
version.
BUG=chrome-os-partner:20034
BRANCH=none
TEST=manual, using gpioget command
1. With AC plugged in, AC_PRESENT=1
2. Press power button. Still AC_PRESENT=1
3. Unplug AC, AC_PRESENT=0
4. Press power button. Still AC_PRESENT=0
