power: supply: qcom: Initial version driver for SMB1398 charger 



This is the initial driver for SMB1398 charger. It can work at CP mode
to provide DIV2 charging mode solution, it can also work as a pre-regultor
which helps to regulate the power from wireless receiver and provides
constant voltage/current input for down streaming chargers.
