Currently dwc3 gadget processes the suspend interrupt event only if the device is in configured state. But consider a case where device is not configured and got suspend interrupt, in that case our gadget would still use 100mA as composite_suspend didn't happen. But battery charging specification (BC1.2) expects a downstream device to draw less than 2.5mA when unconnected OR suspended. And while resuming, the gadget can draw upto 100mA if its not configured, but the current implementation of composite_resume doesnt consider the case of unconfigured device. This series addresses the above mentioned issues.
