spring: Increase CABLE_DET voltage threshold
With this, we can more precisely distinguish a video dongle and an USB
host. The downside is that old boards with ID_OUT connected instead of
CABLE_DET will lose the ability to use a video dongle.
BUG=chrome-os-partner:21310
TEST=Plug in USB host in S5 and see it's detected correctly.
BRANCH=Spring
