power: supply: smb347-charger: Drop pdata support
There are no platforms using the pdata support, so let's drop it to simplify the driver. Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Tested-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>

* If zero value is given in any of the current and voltage values, the
