Jelboz: Dynamic charging current control.
1. Limit Charging Current by thrmal sensor 0 temperature(Charger).
2. If temperature over or under 54C and keep 5s,
Charging Current will change to next level.
3. Limit Charging Current table : 2200/1800/1700/1600
BUG=b:181085004
BRANCH=firmware-zork-13434.B
TEST=make BOARD=shuboz
1. Verified pass by thermal team.
