mb/google/bluey: Check for battery presence in off-mode charging

Browse source 
Verify that a battery is actually present before setting the boot
mode to LB_BOOT_MODE_OFFMODE_CHARGING. This prevents the system
from incorrectly entering a charging state when running on AC power
without a battery connected.

TEST=Build and boot on bluey with and without battery present.
Verify boot mode transitions correctly.
