usb: dwc2: Fix host mode hibernation exit with remote wakeup flow.
[ Upstream commit c2db8d7b9568b10e014af83b3c15e39929e3579e ]
Added setting "port_connect_status_change" flag to "1" in order
to re-enumerate, because after exit from hibernation port
connection status is not detected.
Fixes: c5c403dc4336 ("usb: dwc2: Add host/device hibernation functions")
