thunderbolt: Fix wake configurations after device unplug

Browse source

commit c38fa07dc6 upstream.

Currently we don't configure correctly the wake events after unplug of device
router. What can happen is that the downstream ports of host router will be
configured to wake on: USB4-wake and wake-on-disconnect, but not on
wake-on-connect. This may cause the later plugged device not to wake the
domain and fail in enumeration. Fix this by clearing downstream port's "USB4
Port is Configured" bit, after unplug of a device router.
