usb: chipidea: otg initialization is only needed when the gadget is supported
We have only needed to enable otg initialization when both of below conditions are satisfied: - The controller is otg capable - The gadget function is enabled If the controller is otg capable, but is host-only configuration, we do not need to access register otgsc and do any otg operations (eg, create otg workqueue).
