drawcia: Update OCPC PID constants
drawcia: Update OCPC PID constants

This commit updates the PID constants for drawcia to help minimize the
overshoot and to decrease steady state error more quickly.

BUG=b:174167890
BRANCH=dedede
TEST=Build and flash drawlat; verify that at low SOC, charging from
the sub board results in lower overshoot and reduced time to correct
steady state error.
TEST=Cutoff battery, verify that battery is able to be revived from
sub board.
TEST=Verify DUT can still boot off of AC only.
