Marek Vasut 70728c2946 gpio: syscon: Fix possible NULL ptr usage 
The priv->data->set can be NULL while flags contains GPIO_SYSCON_FEAT_OUT
and chip->set is valid pointer. This happens in case the controller uses
the default GPIO setter. Always use chip->set to access the setter to avoid
possible NULL pointer dereferencing.
