charger: Inhibit power-on until charger is initialized
It's sometimes desirable to boot without a battery, but we may brown out
if we don't have sufficient current. Inhibit AP power-on, even if the system
is unprotected, until our charger and current limit are initialized.
BUG=chrome-os-partner:41258
TEST=Manual on reworked glados with subsequent commit. Remove battery and
attach Zinger. Verify EC powers on and AP doesn't boot. Run `powerbtn`,
verify that AP boots. Remove all power and attach battery, verify that EC
powers on and AP boots.
BRANCH=None
