power: smb: Fix PD ICL configuration flow

Currently, real charger type in case of PD adapter is updated post
ICL configuration. However, ICL configuration routine has a dependency
on the real charger type, henceforth making the ICL configuration
inaccurate. Fix this, by updating the real charger type prior to
ICL configuration.
