nocturne: Disable ACPI AC device

Disable this as we will be using the cros-usb-pd-charger driver for the
USB-C ports on this platform.

Note, this patch will land in stabilize in a different form than on master
since crbug.com/838360 happened.

BUG=b:79781651
TEST=Boot system. Check in /sys/class/power_supply that
CROS_USB_PD_CHARGER0 and CROS_USB_PD_CHARGER1 and BAT0 appear,
but AC does not.
