Rambi: Increase adapter input current limit to 1894mA
This sets the adapter current limit to 90% of the rating for a
40W adapter. The earlier limit was based on a 33W adapter which
was not used.
BUG=chrome-os-partner:23833
BRANCH=ToT
TEST=With a 20-80% charged battery run 4000 fish (search for
WebGl Aquarium) with backlight at 100%. Verify ChargerCurrent
is around the limit with 'adc' command on EC serial console.
