BD9995X: Disable input current limitation for all types of chargers
Charger Operation Control Setting 1 (CHGOP_SET1) has separate bits to
disable input current limitation for DCP, SDP, others. If it is not
disabled, input current is automatically selected, which results in
hard resets on weak chargers hence disable the input current
limitation for all types of chargers.
BUG=chrome-os-partner:60722
BRANCH=none
TEST=Tested on Reef. Input current is not automatically set to all
types of chargers.
