samus: limit input current to 2.5A to prevent over currenting zinger
Set maximum input current limit to ~2.5A to prevent over current
faults on zinger. Note, we still get over current faults sometimes
but it always clears in < 10seconds.
BUG=chrome-os-partner:28611
BRANCH=none
TEST=Test with a samus 1.9 and a zinger. Plug and unplug charger
many times and make sure that we are eventually able to successfully
negotiate for power and start charging.
