Currently a non-root-hub USB device's wakeup settings are initialized when the
device is set to a configured state using device_init_wakeup(), but this is not
correct as wakeup is split into "capable" (can_wakeup) and "enabled"
(should_wakeup).  The settings should be initialized instead in the device
initialization (usb_new_device) with the "capable" setting disabled and the
"enabled" setting enabled.  The "capable" setting should be set based on the
device being configured or unconfigured, and "enabled" setting set based on
the sysfs power/wakeup control.

This patch retains the sysfs power/wakeup setting of a non-root-hub USB device
over a USB device re-configuration, which can happen (for example) after a
suspend/resume cycle.
