Wait for battery boot-up
Some battery uses clock stretching feature, and this could disturb
PMU communication before battery going stable.
AP does not know and will attempt PMU setting, and could get fail
For various battery indicates usually 1s for stable
(even if it is much less in real world 200ms~700ms)
Let's checking 'battery is ready' when first pump-up power.
BUG=chrome-os-partner:28289
TEST=Going battery shipmode and plug-in AC, See booting and EC log
Disconnect battery, and plug-in and see booting and EC log
