Reboots/halts aren't working in healthd charger mode. This is
causing high power draw in an unplugged, powered off state.
Steps to reproduce (on Nexus 5):
Unplug device from USB charger/computer
Turn device off
Wait for device to turn off
Plug in USB cable/charger
Wait for charge animation (wait for animation, not just lightning bolt, may have to press power button briefly to get animation going)
Wait for panel to turn off
Unplug USB cable/charger
Press power button again, notice screen turns on at some frame in the animation.
(not important) Each press of the power button advances the animation
Power on.
