Subject: [PATCH] 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).
