power: smb358-charger: Add BMS controlled termination/recharge

BMS based termination/recharge allows BMS/FG to control charging.
This is useful in cooperation with voltage mode BMS, where due to
a hardware limitation it's required that the EOC and recharge is
always controlled by BMS module.

The BMS module can independently start/stop charging by writing
the STATUS property of battery power-supply. To enable this feature,
following DT params need to be defined:
	qcom,bms-controlled-charging
	qcom,iterm-disabled
