samus: set max input current to something safe
If the input current limit is too high the EC sees the AC_PRESENT signal
toggle rapidly, probably due to the adapter browning out. By
trial-and-error, we found a value that seems to stop that happening.
BUG=chrome-os-partner:23449
BRANCH=samus
TEST=emerge-samus chromeos-ec
Let the battery run down a bit, plug the adapter in, watch the EC console to
see what happens. Make sure it doesn't go nuts.
