USB: don't enable remote wakeup by default
This patch (as1364) avoids enabling remote wakeup by default on all non-root-hub USB devices. Individual drivers or userspace will have to enable it wherever it is needed, such as for keyboards or network interfaces. Note: This affects only system sleep, not autosuspend. External hubs will continue to relay wakeup requests received from downstream through their upstream port, even when remote wakeup is not enabled for the hub itself. Disabling remote wakeup on a hub merely prevents it from generating wakeup requests in response to connect, disconnect, and overcurrent events.
