power_button_x86: Inhibit AP power-on if battery level is too low
Allow CONFIG_CHARGER_MIN_BAT_PCT_FOR_POWER_ON to be defined at the board
level to be the minimum battery percentage required for power-on. If the
battery level is below the threshold, or if the battery is missing,
power button presses will be ignored.
BUG=chrome-os-partner:31127
TEST=Manual on Samus with subsequent commit. Verify that AP continues
to boot normally when charge level exceeds
CONFIG_CHARGER_MIN_BAT_PCT_FOR_POWER_ON. Verify that power button
presses are ignored when the charge level is below the threshold, and
we return to G3.
BRANCH=Samus
