Driver: BD99955: Enable trickle charging
Enabled the trickle charging mode by setting the VPRECHG_TH_SET
register[0x18H] to board specific battery voltage minimum value.
When the battery voltage drops below the battery voltage minimum
value, trickle charging is enabled.
BUG=chrome-os-partner:56684
BRANCH=none
TEST=Manually verified on Reef. Drained the battery below battery
voltage minimum value. On plugging in the charger, State
Machine Status register CHGSTM_STATUS [0x00h] is 0x01 which
indicates, current state of the charger state-machine is in
Trickle-Charge condition.
