Read VS (Version) register as part of controller initialization instead of controller construction. This prepares for upcoming changes to make controller attach fully asynchronous. Since reading fabrics registers is an asynchronous operation, it will be easier to read the VS register as part of controller initialization which operates as an asynchronous state machine.
