spring: Shorten delay for charger redetect
It takes ~250ms for TSU6721 to recognize a CDP charger. Let's shorten
the redetecting delay from 4 seconds to 600ms so that:
1. A CDP charger is recognized faster
2. We can properly detect overcurrent for CDP charger
BUG=chrome-os-partner:21388
TEST=Plug in a CDP charger and see it recognized after 600ms.
BRANCH=Spring
