power: smb5: initialize Type-C to DRP mode on boot 



When the device is shutdown/reboot with a charger connected, some of the
charger related PMIC configurations won't get reset because VBUS is
present.

This can cause issues like detecting a sink device. Currently, Type-C/PMIC
is always forced into sink mode right before shutdown, which, if not
altered after boot, will fail subsequent sink device connections.

Fix it by resetting Type-C to DRP mode on boot.
