Current fast charge assumes only one battery voltage threshold range for
charger profile override. However we have multiple battery voltage
threshold ranges for few batteries hence added a code which can consider
multiple battery threshold ranges and choose respective charge profile.
BUG=chrome-os-partner:62653
BRANCH=none
TEST=Manually tested on Electro. Manipulate smp_cos4870 & sonycorp
battery voltage & temperature ranges and observed correct charge
profile is selected.
