spring: Check USB device type periodically
The device type reported by TSU6721 changed rapidly in some cases, and
we miss the change after the first one. We need to check device type
change periodically.
BUG=chrome-os-partner:20336
TEST=Plug and unplug DCP charger in suspend. Check device type is
detected correctly.
BRANCH=Spring
