power: override USB ICL

Browse source 
Override USB ICL using the targer ICL value, so that
the ICL settled value will not be limited to a lower
value than target value.
For example, when connect device using a CC floated
typec cable, the settled icl will be set to 100mA,
which will block the charging.
