USB: Add call to notify xHC of a device reset.
Add a new host controller driver method, reset_device(), that the USB core
will use to notify the host of a successful device reset. The call may
fail due to out-of-memory errors; attempt the port reset sequence again if
that happens. Update hub_port_init() to allow resetting a configured
device.
