Devicetree based platforms don't handle device callbacks very well and until now no board has come along that needs more extended hwinit than pulling the rst gpio high. Therefore pull the reset handling directly into the driver and remove the callbacks from the driver. If extended device setup is needed at some later point, power-sequences would probably be the solution of choice.
